  • Analysis of the Joint Viterbi Detector/Decoder (JVDD) Over a Coded
           AWGN/ISI System ss an LDPC Alternative
    • Authors: Kheong Sann Chan;Susanto Rahardja;
      Pages: 1 - 9
      Abstract: The joint Viterbi detector/decoder (JVDD) has been proposed as an alternative to the powerful and ubiquitous low-density parity check (LDPC) coding schemes, that are used in the majority of channel coding applications today. At shorter block lengths, the JVDD is able to outperform the state-of-the-art LDPC decoder that can be found in many of today's systems, from deep-space communications to the digital video broadcasting standard, to the advanced television standard committee 3.0. Researchers have developed the tools to analyze the performance of the LDPC decoder, which is known as the sum-product algorithm or message passing algorithm. These tools include density evolution (DE) and extrinsic information transfer (EXIT) charts. To date, no similar such analysis exists for the JVDD. In the current paper we perform a similar preliminary analysis on the JVDD algorithm akin to what DE and EXIT charts are for the LDPC decoder. The current new analysis of the JVDD allows prediction of its probability of error based on the probability distribution functions of the metrics used within the algorithm. Our analysis plays a similar role to the abovementioned tools developed for the LDPC decoder: it allows us to predict the performance of the JVDD under various conditions (such as varying SNR's, thresholds, and block lengths), it improves our understanding of the JVDD algorithm and the match against Monte-Carlo simulations verifies our assumptions on the main error-causing mechanisms within the JVDD.

  • Low Complexity Adaptive Demapper for 2-D Non-Uniform Constellations
    • Authors: Jon Barrueco;Jon Montalban;Pablo Angueira;Charbel Abdel Nour;Catherine Douillard;
      Pages: 10 - 19
      Abstract: In this paper, a novel demapper for 2-D non-uniform constellations (2D-NUCs) is proposed, exploiting the characteristics of these constellations. It represents the combination of two underlying demapping techniques targeting the ATSC 3.0 compliant OFDM transceiver. On the one hand, for low code rates, we define a metric to perform condensed demapping. On the other hand, for high code rates, adaptive sub-region demapping is proposed. In this paper, a combination of both demapping methods is designed showing comparable performance to the classical ML demapper. The gap does not exceed 0.1 dB for all code rates of the ATSC 3.0 standard. Higher complexity reduction, from 79.2% to 95.4%, than state of art 2D-NUC demappers is obtained for 2D-256NUCs. These results are validated for ideal and non-ideal channel state information over additive white noise Gaussian and Rayleigh independently and identically distributed channels. Results are extended to 2D-1kNUCs and 2D-4kNUCs showing demapping complexity reduction from 96% to 99.7% with a negligible impact on performance.

  • Spatial Modulation Aided Layered Division Multiplexing: A Spectral
           Efficiency Perspective
    • Authors: Yue Sun;Jintao Wang;Changyong Pan;Longzhuang He;Bo Ai;
      Pages: 20 - 29
      Abstract: In this paper, spatial modulation (SM) is introduced to layered division multiplexing (LDM) systems for enlarging the spectral efficiency (SE) over broadcasting transmission. First, the SM aided LDM (SM-LDM) system is proposed, in which different layered services utilize SM for terrestrial broadcasting transmission with different power levels. Then a SE analysis framework for SM-LDM systems is proposed, which is suitable for the SM-LDM systems with linear combining. Moreover, the closed-form SE lower bound of SM-LDM systems with maximum ratio combining (MRC) is derived, which is based on this framework. Since the theoretical SE analysis of single transmit antenna (TA) LDM systems with MRC and spatial multiplexing (SMX) aided LDM systems with MRC lacks a closed-form expression, the closed-form SE is also derived for these systems. Monte Carlo simulations are provided to verify the tightness of our proposed SE lower bound. Furthermore, it can be shown via simulations that our proposed SM-LDM systems always have a better SE performance than single-TA LDM systems, which can even outperform the SE of SMX aided LDM (SMX-LDM) systems.

  • Layered Division Multiplexing With Distributed Multiple-Input
           Single-Output Schemes
    • Authors: Eduardo Garro;Carlos Barjau;David Gomez-Barquero;Jeongchang Kim;Sung-Ik Park;Namho Hur;
      Pages: 30 - 39
      Abstract: Single frequency networks (SFNs) provides an increased spectral efficiency compared to the traditional multiple frequency networks. However, some coverage areas in SFN can be affected by destructive interferences. In order to reduce these situations, distributed multiple-input single-output (MISO) schemes have been adopted in the new digital terrestrial television standards, Alamouti in DVB-T2 and transmit diversity code filter sets in ATSC 3.0. On the other hand, layered division multiplexing (LDM), a non-orthogonal multiple access technology, has been adopted in ATSC 3.0 due to its spectral efficiency increase compared to time or frequency division multiplexing. The LDM signal is formed by a power superposition of two independent signals, which are designed for different reception conditions (mobile and fixed-rooftop). The combination of distributed MISO and LDM techniques has not been evaluated yet. In this paper, the joint transmission of LDM with distributed MISO is analyzed in terms of complexity and the joint performance is evaluated by means of physical layer simulations.

  • Using Layered-Division-Multiplexing to Deliver Multi-Layer Mobile Services
           in ATSC 3.0
    • Authors: Liang Zhang;Wei Li;Yiyan Wu;Khalil Salehian;Sébastien Laflèche;Zhihong Hong;Sung-Ik Park;Heung Mook Kim;Jae-Young Lee;Namho Hur;Xianbin Wang;Pablo Angueira;Jon Montalban;
      Pages: 40 - 52
      Abstract: Layered-division-multiplexing (LDM) is a physical-layer non-orthogonal multiplexing technology, which has been accepted as a baseline technology by the next generation terrestrial digital TV (DTV) broadcasting standard, advanced television systems committee (ATSC) 3.0. The typical scenario for an LDM-based ATSC 3.0 system is to deliver a robust high-definition TV (HDTV) service in the higher-power core-layer (CL) for mobile reception and a 4k ultra high definition TV or multiple enhanced full HDTV (1080p) services in the lower-power enhanced layer (EL) for fixed reception. So far, the capability of using the EL of an LDM system to deliver mobile services has not been investigated and well-understood. In this paper, we investigate the potential of using both layers of an LDM-based ATSC 3.0 system to delivery multiple mobile services that target different types of mobile devices. The mobile performance of the LDM system is then compared to its time-division-multiplexing and frequency-division-multiplexing counterparts, which will reveal the application scenarios for which using LDM would provide performance advantages. In addition, the availability of high-throughput fixed services carried in the LDM-EL to mobile receivers is also investigated by computer simulations. An advanced detection algorithm is proposed based on the LDM-CL inter-carrier-interference cancellation, which is shown to provide significantly better mobile performance. Finally, we show by simulation that using receive antenna diversity combining techniques can significantly improve the service detection performance of LDM mobile receivers, especially for services carried in the LDM EL.

  • Key Technologies and Measurements for DTMB-A System
    • Authors: Jian Song;Chao Zhang;Kewu Peng;Jintao Wang;Changyong Pan;Fang Yang;Jun Wang;Hui Yang;Yonglin Xue;Yu Zhang;Zhixing Yang;
      Pages: 53 - 64
      Abstract: Digital terrestrial television multimedia broadcasting-advanced (DTMB-A), the new digital terrestrial television broadcasting (DTTB) system proposed by China, has been accepted by International Telecommunications Union as the international DTTB standard in July, 2015. By adopting several advanced technologies, such as near-capacity channel coding and modulation as well as improved frame structure, DTMB-A can provide faster system synchronization, higher receiving sensitivity, better performance against multipath effect, higher spectrum efficiency, and the flexibility for future extension, compared with its previous generation, DTMB system. This paper provides the technical analyses on the physical layer specifications of DTMB-A system in detail, together with the discussion on the key technologies adopted. Laboratory test and field trial results are also given which demonstrate that DTMB-A can offer excellent overall system performance for both fixed and mobile receptions under complicated terrestrial broadcasting conditions, and is capable of supporting multiple services with different quality of service requirements.

  • Precoding for Flexible High Throughput Satellites: Hot-Spot Scenario
    • Authors: Giorgio Taricco;Alberto Ginesi;
      Pages: 65 - 72
      Abstract: Motivated by the need of resource flexibility in high throughput satellite systems, a hot-spot cell configuration is introduced and analyzed in terms of throughput performance. Cell partitioning and user scheduling are also addressed in conjunction with the application of different types of linear precoding algorithms. The analysis is based on a real satellite system design and uses a system simulation approach, encompassing the random user distribution inside the hot-spot cell area. Results provide guidelines on the design of the hot-spot cell partitioning and show the achievable gains of precoding with respect to conventional, non precoded, transmission.

      Pages: 73 - 82
      Abstract: In addition to the traditional TDM/FDM, the advanced television systems committee (ATSC) 3.0 next generation digital TV standard has adopted state-of-the-art coding and modulation, as well as the new layered division multiplexing (LDM) technology. The ATSC 3.0 system is able to provide higher data throughput, more robust reception, better spectrum efficiency, and flexible service combinations in one RF channel with different robustness and reception conditions. Due to the adoption of a two-layer LDM, the coverage for ATSC 3.0 is very different from the legacy one-transmitter-one-coverage ATSC 1.0 system. With the new enabling technologies, the ATSC 3.0 can greatly increase the coverage/service areas, reduce the distance between co-channel assignments, and introduce local program insertion and targeted advertisement. This paper addresses the ATSC 3.0 coverage and co-channel interference issues, by using the two-layer LDM technology with different operating parameters. Simulations demonstrate that, similar to the 4G long term evolution, the ATSC 3.0 co-channel assignment could be reduced to two times the service coverage radius. This means an improvement of the spectrum efficiency by up to four times in comparison with today's system. It is also proved through simulations that significant TV program gains can be obtained with this new system. The deployment of single frequency networks can further improve the coverage and reduce the interference.

  • A Hybrid Unicast-Multicast Network Selection for Video Deliveries in Dense
           Heterogeneous Network Environments
    • Authors: Giuseppe Araniti;Pasquale Scopelliti;Gabriel-Miro Muntean;Antonio Iera;
      Pages: 83 - 93
      Abstract: Resource management in emerging dense heterogeneous network environments (DenseNets) is a challenging issue. The employment of multicast transmissions in this scenario has potential to address the problems. On one hand, the large number of smart user mobile devices and user expectations for high-quality rich media services has determined a growing demand for network resources; in DenseNets, mobile users have to make the choice in terms of the network to connect to, in order to balance energy saving and delivery performance. On the other hand, the proliferation of user accesses to the existing and future network infrastructure will bring along with it the operators need for optimizing the radio resource usage. This paper proposes a hybrid unicast-multicast utility-based network selection algorithm (HUMANS), which offers the additional option of selecting multicast transmissions in the network selection process during video delivery. By serving users with good channel conditions via unicast transmissions and users with poor channel quality conditions via multicast, HUMANS allows outperforming other solutions in terms of outage percentage and average quality of transmission, in both low- and high-density scenarios. Most importantly, at the same time it guarantees operators a more efficient resource utilization.

  • Data-Driven Rate Control for Rate-Distortion Optimization in HEVC Based on
           Simplified Effective Initial QP Learning
    • Authors: Wei Gao;Sam Kwong;Qiuping Jiang;Chi-Keung Fong;Peter H. W. Wong;Wilson Y. F. Yuen;
      Pages: 94 - 108
      Abstract: Different from the conventional calculative methods, a learning-based initial quantization parameter (LIQP) method is proposed in this paper to improve rate control of high efficiency video coding (H.265). First, the framework for initial quantization parameter (QP) learning is proposed, where a novel equivalent approach to build the benchmark labels is proposed using the single rate-distortion (R-D) pair in each initial QP testing. With the criterion of maximizing the prediction accuracy of initial QPs, features and parameters of the learning model are refined. Instead of the traditionally used target bits per pixel (bpp) for intraframe, the target bpp for all remaining frames is proposed to avoid the empirical setting on intracoding bits, and thus the related inaccuracy can be prevented. We clearly present the motivations of the proposed LIQP method, as well as the reasons for the extracted features and model parameters. The proposed LIQP method outperforms the latest HM-16.14 by achieving significant gains on R-D performance (-15.48% BD-BR and 0.782 dB BD-PSNR gains), quality smoothness (1.581 dB versus 2.598 dB), and more stable buffer occupancy control, with similar high bit rate accuracy (99.84% versus 99.87%), and can also work well for scene change cases.

  • Fast HEVC Intra Mode Decision Based on RDO Cost Prediction
    • Authors: Mohammadreza Jamali;Stéphane Coulombe;
      Pages: 109 - 122
      Abstract: High efficiency video coding (HEVC) increases the number of intra coding modes to 35 to provide higher coding efficiency than previous video coding standards. This results in an increased encoder complexity, since there are more modes to be processed by the high resource-demanding rate-distortion optimization (RDO). In this paper, we propose a novel method to reduce the HEVC intra mode decision computational complexity and encoding time. This method is based on the prediction of the RDO cost of intra modes from a low-complexity sum of absolute transformed differences-based cost. By predicting the RDO cost, we are able to exclude non-promising modes from further processing and thereby save substantial computations. Also, a gradient-based method, using the Prewitt operator, is proposed to eliminate the non-relevant directional modes from the list of candidates. For even more complexity reduction, a mode classification is proposed to adaptively reduce chroma intra modes based on block texture. Experimental results show that we achieve a 47.3% encoding time reduction on average with a negligible quality loss of 0.062 dB for the Bjøntegaard delta peak signal-to-noise ratio when we compare our method to the HEVC test model 15.0.

  • Global Auto-Regressive Depth Recovery via Iterative Non-Local Filtering
    • Authors: Jingyu Yang;Xinchen Ye;Pascal Frossard;
      Pages: 123 - 137
      Abstract: Existing depth sensing techniques have many shortcomings in terms of resolution, completeness, and accuracy. The performance of 3-D broadcasting systems is therefore limited by the challenges of capturing high-resolution depth data. In this paper, we present a novel framework for obtaining high-quality depth images and multi-view depth videos from simple acquisition systems. We first propose a single depth image recovery algorithm based on auto-regressive (AR) correlations. A fixed-point iteration algorithm under the global AR modeling is derived to efficiently solve the large-scale quadratic programming. Each iteration is equivalent to a nonlocal filtering process with a residue feedback. Then, we extend our framework to an AR-based multi-view depth video recovery framework, where each depth map is recovered from low-quality measurements with the help of the corresponding color image, depth maps from neighboring views, and depth maps of temporally adjacent frames. AR coefficients on nonlocal spatiotemporal neighborhoods in the algorithm are designed to improve the recovery performance. We further discuss the connections between our model and other methods like graph-based tools, and demonstrate that our algorithms enjoy the advantages of both global and local methods. Experimental results on both the Middleburry datasets and other captured datasets finally show that our method is able to improve the performances of depth images and multi-view depth videos recovery compared with state-of-the-art approaches.

  • Full-Reference Image Quality Assessment by Combining Features in Spatial
           and Frequency Domains
    • Authors: Zhisen Tang;Yuanlin Zheng;Ke Gu;Kaiyang Liao;Wei Wang;Miaomiao Yu;
      Pages: 138 - 151
      Abstract: Objective image quality assessment employs mathematical and computational theory to objectively assess the quality of output images based on the human visual system (HVS). In this paper, a novel approach based on multifeature extraction in the spatial and frequency domains is proposed. We combine the gradient magnitude and phase congruency maps to generate a local structure (LS) map, which can perceive local structural distortions. The LS matches well with HVS and highlights differences with details. For complex visual information, such as texture and contrast sensitivity, we deploy the log-Gabor filter, and spatial frequency, respectively, to effectively capture their variations. Moreover, we employ the random forest (RF) to overcome the limitations of existing pooling methods. Compared with support vector regression, RF can obtain better prediction results. Extensive experimental results on the five benchmark databases indicate that the proposed method precedes all the state-of-the-art image quality assessment metrics in terms of prediction accuracy. In addition, the proposed method is in compliance with the subjective evaluations.

  • Reduced Reference Quality Assessment of Light Field Images
    • Authors: Pradip Paudyal;Federica Battisti;Marco Carli;
      Pages: 152 - 165
      Abstract: Immersive media, such as free view point video and 360° video, are expected to be dominant as broadcasting services. The light field (LF) imaging is being considered as a next generation imaging technology offering the possibility to provide new services, including six degree-of-freedom video. The drawback of this technology is in the size of the generated content thus requiring novel compression systems and the design of ad-hoc methodologies for evaluating the perceived quality. In this paper, the relation between depth map quality and overall quality of LF image is studied. Next, a reduced reference quality assessment metric for LF images is presented. To predict the quality of distorted LF images, the measure of distortion in the depth map is exploited. To test and validate the proposed framework, a subjective experiment has been performed, and a LF image quality dataset has been created. The dataset is also used for evaluating the performance of state-of-the-art quality metrics, when applied to LF images. The achieved results evidence that the estimated quality score by the proposed framework has a significant correlation with subjective quality rating. Consequently, reference data can be delivered to the clients thus allowing the local estimation of the perceived quality of service.

  • Performance Analysis of LDPC-BICM System Based on Gaussian Approximation
    • Authors: Genning Zhang;Yin Xu;Dazhi He;Jun Sun;Wenjun Zhang;
      Pages: 166 - 171
      Abstract: In this paper, we propose a performance analysis algorithm of low density parity check-bit interleaved coded modulation (LDPC-BICM) system. First, we introduce the Gaussian mixture approximation method of the LLR messages output from the demodulator over the AWGN channel. Then, we analyze the density evolution based on these Gaussian mixture approximation LLR messages. During the analysis, the Gaussian approximation is applied to simplify the calculation. Some LDPC-BICM systems (which are adopted by ATSC3.0 standard) are used to evaluate the proposed algorithm. We also employ the actual performances and the thresholds obtained by the multi-edge type (MET) discretized density evolution algorithm as the references. The simulation results prove that our proposed algorithm can work well in most cases. Furthermore, the proposed algorithm is simpler than the MET algorithm because of the Gaussian or Gaussian mixture approximations.

  • Performance Analysis of Practical QC-LDPC Codes: From DVB-S2 to ATSC 3.0
    • Authors: Shuang Chen;Kewu Peng;Jian Song;Yushu Zhang;
      Pages: 172 - 178
      Abstract: In this paper, a new analysis method is introduced to predict the gap between Shannon limit and successful decoding signal-to-noise ratio threshold (SNR loss) of practical quasi-cyclic low-density parity check (QC-LDPC) codes. The SNR loss of a QC-LDPC code is summed up from three aspects: 1) the base matrix; 2) the number of iterations for decoding; and 3) the finite codeword length. As an example, the SNR loss of DVB-S2 and ATSC 3.0 LDPC codes is analyzed with the proposed method. Results show that a large portion of the SNR loss of DVB-S2 LDPC codes is due to their base matrices, which is significantly improved in latest ATSC 3.0 standard. Furthermore, with the aid of the proposed analysis method, newly designed QC-LDPC codes with raptor-like structure are proposed. Bit-error rate simulations show that the proposed codes are only 0.4 dB away from Shannon limit under binary-input additive white Gaussian noise channel and only 0.65 dB away from Shannon limit under binary-input Rayleigh fading channel, which are comparable with state-of-art design.

  • A Fairness–Throughput Tradeoff Perspective on NOMA Multiresolution
           Broadcasting
    • Authors: Adriano Pastore;Monica Navarro;
      Pages: 179 - 186
      Abstract: We propose an analytical framework for characterizing the tradeoff between fairness and throughput that arises in a cellular or satellite downlink when multicast information is encoded in two resolution levels (high versus low priority information). Given a target fairness (measured in terms of the ratio between the information rates of low versus high resolution stream), the operator seeks to optimize the modulation and coding schemes so as to maximize the average cell throughput. Viewing operating points as fairness-throughput pairs allows to meaningfully quantify and interpret the superiority of non-orthogonal multiple access techniques such as superposition coding against simple orthogonal time division. The optimal fairness-throughput tradeoff curve for superposition coding versus time division is derived in the Gaussian setting. A practical implementation with 16-QAM constellations and multilevel coding is proposed and its tradeoff curve is numerically evaluated.
