  • Performance Analysis of All Modulation and Code Combinations in ATSC 3.0
           Physical Layer Protocol
    • Authors: Sung-Ik Park;Jae-Young Lee;Sunhyoung Kwon;Bo-Mi Lim;Sungjun Ahn;Heung Mook Kim;Sungho Jeon;Jaekwon Lee;Michael Simon;Mark Aitken;Kevin Gage;Yiyan Wu;Liang Zhang;Wei Li;Jeongchang Kim;

      Abstract: This paper presents the advanced television systems committee (ATSC) 3.0 physical layer system performances with different modulation and channel coding combinations. Numerous computer simulations, laboratory tests, and field trials are conducted under additive white Gaussian noise, RC20, and RL20 channels. Analysis of the results shows that the measured values in laboratory and field are less than 1 dB away from computer simulation results. This confirms that the ATSC 3.0 physical layer is capable of providing services ranging from ultra-robust reception (negative SNR operation with QPSK and 2/15 low density parity check (LDPC) code) to very high-throughput (over 50 Mb/s with 4096-non-uniform constellation and 13/15 LDPC code) in real field environments.

  • A Novel Iterative Detection Scheme of Bootstrap Signals for ATSC 3.0
    • Authors: Hyeongseok Kim;Jeongchang Kim;Sung-Ik Park;Namho Hur;Michael Simon;Mark Aitken;
      Pages: 211 - 219
      Abstract: This paper derives a maximum-likelihood decision rule to detect the signaling information conveyed by the bootstrap for an ATSC 3.0 system and proposes an iterative detection scheme to improve the detection performance. The proposed detection scheme iteratively averages the channel estimates for two consecutive bootstrap symbols by exploiting the previously detected symbol. The simulation results show that the proposed detection scheme can obtain a signal-to-noise ratio gain of approximately 2.0 dB at a frame error rate of $10^{-3}$ compared to the conventional detection scheme. Furthermore, this paper analyzes the computational complexity of the proposed detection scheme and presents the number of iterations sufficient to provide a good performance-complexity trade-off.

  • Line of Sight Component Identification and Positioning in Single Frequency
           Networks Under Multipath Propagation
    • Authors: Ruiqi Liu;Chao Zhang;Jian Song;
      Pages: 220 - 233
      Abstract: Broadcasting signals have been recognized as promising candidates for navigation and positioning needs. However, in most single frequency broadcasting networks, the transmitter confusion problem poses a huge obstacle. Not holding the transmitter identities, the receiver cannot determine the distance to the transmitters, let alone its own position. What’s worse, considering the existence of multipath propagation, the receiver is unable to distinguish line of sight (LOS) components from non line of sight components, which makes positioning even harder. In this paper, a two-step method is proposed to solve the positioning problem in single frequency networks (SFNs) under multipath propagation yet with direct path. First, a probability approach is proposed to identify all LOS components iteratively. Then, it is proved in this paper that a receiver can determine its position when receiving LOS signals from at least five transmitters without the knowledge of transmitter identities. Detailed analysis is carried out in this paper to derive error bounds and performance limits from different perspectives. Simulation results show that the proposed algorithm can achieve high accuracy of positioning across multiple environments. Besides, the proposed methodology is general, which can be used in any SFN or other wireless networks for positioning needs.

  • Partial-Data Superimposed Training With Data Precoding for OFDM Systems
    • Authors: Juan Carlos Estrada-Jiménez;M. Julia Fernández-Getino García;
      Pages: 234 - 244
      Abstract: Superimposed training (ST) is a recently addressed technique used for channel estimation where known training sequences are arithmetically added to data symbols, avoiding the use of dedicated pilot subcarriers, and thus, increasing the available bandwidth compared with traditional pilot symbol assisted modulation schemes. However, the system handles data interference over channel estimation as a result of the ST process; also, data detection is degraded by pilot interference. Recent ST methods have analyzed the data interference and presented schemes that deal with it. We propose a novel superimposed model over a precoded data scheme, named partial-data superimposed training (PDST), where an interference control factor assigns the adequate information level to be added to the training sequence in orthogonal frequency division multiplexing systems. Also, a data detection method is introduced to improve the symbol error rate performance. Moreover, a capacity analysis of the system has been derived. Finally, simulation results confirm that performance of PDST is superior to previous proposals.

  • Joint Design for Modulation and Constellation Labels in Multiuser
           Superposition Transmission
    • Authors: Baicen Xiao;Kexin Xiao;Zhiyong Chen;Bin Xia;Hui Liu;
      Pages: 245 - 259
      Abstract: Hierarchical modulation (HM), a promising non-orthogonal multiple access scheme, is able to provide different levels of protection for data streams and achieve a larger rate region that cannot be realized by traditional orthogonal schemes. In this paper, we propose a novel HM system with non-uniform constellation inputs and analytically derive the bit-interleaved coded modulation (BICM)-capacity for each hierarchical layer. Different from the power optimization method for the superimposed uniform constellation, we directly optimize the constellation positions in conjunction with the optimal binary labels design for HM in additive white Gaussian noise channels. For maximizing the BICM-capacity, a fairness balanced criteria is developed for the HM system by considering both power constraints and QoS constraints. Multi-start interior-point algorithm is then proposed to carry out the constellation optimization problems, and the corresponding methods are also proposed to reduce optimization complexity. Numerical results verify the performance gains of optimized HM compared with the optimized quadrature amplitude modulation based HM and other orthogonal transmission methods.

  • Prototype Filter Design to Minimize Stopband Energy With Constraint on
           Channel Estimation Performance for OQAM/FBMC Systems
    • Authors: Yuan Tian;Da Chen;Kai Luo;Tao Jiang;
      Pages: 260 - 269
      Abstract: In this paper, we propose a prototype filter design method to minimize the stopband energy of the filter with guaranteed time-domain channel estimation performance for offset quadrature amplitude modulation based filter bank multicarrier (OQAM/FBMC) systems. First, we analytically derive the total mean squared error (MSE) of estimated channel impulse response with two channel estimation schemes, i.e., the linear minimum mean square error and weighted least square, where the impact of intrinsic interference from data symbols is taken into account. Then, we formulate an optimization problem of filter coefficients to minimize the stopband energy with constraint on the total MSE. By exploiting the Heisenberg–Gabor uncertainty principle, the original optimization problem is transformed into an equality-constrained one. Finally, we employ the Lagrange multiplier method to solve the transformed problem and obtain the filter coefficients with the Newton’s method. Simulation results demonstrate that the proposed filter outperforms the isotropic orthogonal transform algorithm and extended Gaussian function filters considering both the MSE and stopband energy performances.

  • Optimal Bit Allocation at Frame Level for Rate Control in HEVC
    • Authors: Hongwei Guo;Ce Zhu;Shengxi Li;Yanbo Gao;
      Pages: 270 - 281
      Abstract: Rate control plays an important role in video coding systems, which makes the output bitrate of a video encoder equal to the target bitrate while minimizing the distortion of the compressed video. However, most of the existing rate control schemes achieve accurate bitrate control at the loss of rate-distortion (R-D) performance. This paper proposes an effective frame level bit allocation method to improve the R-D performance whilst maintaining the high accuracy of the bitrate control in HEVC. First, an improved R-D model is presented at the frame level, which, by making use of the information of encoded frames more completely, achieves higher accuracy with lower bitrate mismatch rate. Second, a group of picture (GOP) level bit allocation approach is introduced with the consideration of the temporal R-D dependency among different GOPs, which can further enhance the R-D performance. Finally, to achieve optimal R-D performance globally, a formulation for optimal frame level bit allocation is developed with a GOP level Lagrange multiplier introduced, which takes into account the coding effects of a current frame on the other frames within the same GOP. A scheme of recursive Taylor expansion is employed to find the GOP level Lagrange multiplier. Experimental results demonstrate that the proposed method can achieve considerable R-D performance improvement and accurate bitrate control. Specifically, our method shows 3.9% and 3.8% BD-rate saving in average compared against the HEVC reference software HM16.7 with rate control in the low-delay B and low-delay P coding structures, respectively.

  • Error Concealment-Aware Encoding for Robust Video Transmission
    • Authors: João F. M. Carreira;Pedro A. Assunção;Sérgio M. M. de Faria;Erhan Ekmekcioglu;Ahmet Kondoz;
      Pages: 282 - 293
      Abstract: In this paper an error concealment (EC)-aware encoding scheme is proposed to improve the quality of decoded video in broadcast environments subject to transmission errors and data loss. The proposed scheme is based on a scalable coding approach where the best EC methods to be used at the decoder are optimally determined at the encoder and signalled to the decoder through supplemental enhancement information messages. Such optimal EC modes are found by simulating transmission losses, followed by a Lagrangian optimization of the signalling rate—EC distortion cost. A generalized saliency-weighted distortion is used and the residue between coded frames and their EC substitutes is encoded using a rate-controlled enhancement layer. When data loss occurs the signalling information is used by the decoder to improve the reconstruction quality. The simulation results show that the proposed method achieves consistent quality gains in comparison with other reference methods and previous works. Using only the EC mode signalling, i.e., without any residue transmitted in the enhancement layer, an average PSNR gain up to 2.95 dB is achieved, while using the full EC-aware scheme, i.e., including residue encoded in the enhancement layer, the proposed scheme outperforms other comparable methods, with a PSNR gain up to 3.79 dB.

  • Color Correction and Depth-Based Hierarchical Hole Filling in Free
           Viewpoint Generation
    • Authors: Yiguo Qiao;Licheng Jiao;Shuyuan Yang;Biao Hou;Jie Feng;
      Pages: 294 - 307
      Abstract: In this paper, a high-quality depth-image-based-rendering-based free viewpoint generation model is proposed, which consists of three parts. First, a boundary-aware 3-D warping is introduced for projecting the side views from original view plane to target virtual view plane. Specifically, a high-pass filter is used to remove the ghost contours along object boundaries. Second, a color correction-based image blending (CC-IB) procedure is put forward for synthesizing the two warped side views. During the proposed CC-IB, occluded regions are color-corrected and reconstructed in the first place, on the basis of an equivalent substitution thought and a polynomial fitting method, then color-continuous virtual view can be produced by blending the un-occluded regions and the reconstructed disocclusions. Finally, a depth guided hierarchical hole-filling method is presented for filling the remaining holes in the blended virtual view. With the assistance of depth, background pixels are preferentially selected for filling the holes. Experimental results show that the proposed model can produce high-quality virtual views with comfortable visual perceptions. Comparisons with other state-of-the-art models demonstrate that the proposed method can achieve good performance in both visual quality and quantitative evaluation.

  • Ping-Pong Joint Optimization of PAPR Reduction and HPA Linearization in
           OFDM Systems
    • Authors: Rafik Zayani;Hmaied Shaïek;Daniel Roviras;
      Pages: 308 - 315
      Abstract: In this paper, we introduce a joint approach for peak-to-average power ratio (PAPR) reduction and predistortion for orthogonal frequency division multiplexing systems subjected to strong memoryless nonlinearity. The proposed approach is new and promising concept that consists in a really synergistic combination of the two operations in order to improve power amplifier efficiency and linearity. Its key idea is to synthesize a correction signal in a Ping-Pong manner between PAPR reduction and predistortion. The proposed Ping-Pong joint optimization approach provides significant improvement, compared to conventional schemes, in system energy efficiency while fulfilling out-of-band requirements and preserving low in-band distortion.

  • Reduction of PAPR Without Side Information for SFBC MIMO-OFDM Systems
    • Authors: Wei-Wen Hu;Wan-Jen Huang;Ying-Chi Ciou;Chih-Peng Li;
      Pages: 316 - 325
      Abstract: A novel peak-to-average power ratio (PAPR) reduction scheme designated as extended selected mapping (eSLM) is proposed for space-frequency block coding (SFBC) multi-input multi-output orthogonal frequency division multiplexing systems. In the eSLM method, extension matrices comprising amplitude extensions and phase rotations are constructed to indicate the selected signal index without the need for side information and to minimize the PAPR, respectively. To reduce the computational complexity incurred by the inverse discrete Fourier transform operation in generating the candidate signals, a low-complexity eSLM scheme (LC-eSLM) is developed by constructing equivalent candidate signals in the time domain. Notably, the extension matrices in both schemes preserve the orthogonality of the SFBC code, thereby facilitating low-complexity decoding. The simulation results show that the proposed eSLM scheme not only outperforms existing blind SLM-based methods. Compared with the costly ordinary SLM scheme, the eSLM scheme has a lower computational complexity with a performance loss of less than 0.3 dB and requires no side information. Furthermore, the computational complexity of the LC-eSLM scheme is around 40%–50% lower than that of the eSLM scheme with only a marginal degradation in the PAPR reduction performance.

  • Efficient ATSC 3.0 TxID Signal Detection for Single Frequency Networks
    • Authors: Jaekwon Lee;Sungho Jeon;Sung-Ik Park;Dong Ku Kim;
      Pages: 326 - 332
      Abstract: Single-frequency network (SFN) can be applied to advanced television systems committee (ATSC) 3.0-based terrestrial broadcasting systems to improve the service availability and quality of service without additional spectral resources. The main problem of SFN planning is the co-channel interference caused by multiple transmitters that use the same radio frequency for signal transmission and reception. The effect of the co-channel interference can be minimized by adjusting the network delay and transmit power of multiple transmitters within the SFN coverage area. To adjust the delay and power, it is necessary to estimate the channel impulse response (CIR) from each transmitter to a receiver. To support this process, a transmitter identification (TxID) signal is embedded in an original ATSC 3.0 signal. At the receiver, the individual CIR may be measured by a correlation-process-based TxID detection. However, since the correlation process may require large computational efforts, it is a quite challenging work to design a TxID detection algorithm with reduced complexity. This paper proposes a low-complexity TxID detection algorithm. The design and performance of the proposed algorithm is investigated and analyzed through numerical simulations. The simulation results indicate that the proposed algorithm can offer almost the same performance as the conventional TxID detection algorithm with significantly reduced complexity.

      Abstract: In this paper, an efficient symbol timing offset (STO) and sampling frequency offset (SFO) estimation scheme is proposed in an orthogonal frequency division multiplexing-based digital radio mondiale system using cyclic delay diversity. By using a periodic nature of channel transfer function, cyclic delay and pilot pattern with a maximum channel power are chosen, which aids to enable a robust estimation of STO and SFO against frequency selectivity of the channel. As a performance measure, the mean squared error of the proposed scheme is theoretically derived and is verified through simulations. By simulation results, the proposed estimation scheme is proved to profit from properly selected cyclic delay and pilot pattern, with a superior performance over the conventional estimation scheme.

      Abstract: Whilst broadband Internet connectivity has become highly important, providing broadband connectivity nonetheless remains a considerable challenge, particularly in rural and remote regions where the deployment of optical fibers faces economical obstacles. A promising option to address this issue is that of the most recent satellite systems, capable of providing high capacities virtually everywhere. However, compared to most terrestrial systems, satellite networks have very different link and, more importantly, latency characteristics, which often render them only barely usable for delay intolerant traffic. Thus, convergence of terrestrial and satellite networks is required, so that only certain traffic flows can be offloaded onto a supplemental satellite connection. In this paper, we propose a network architecture relying on modern software defined network concepts, which enable dynamic traffic offloading in a converged satellite and terrestrial network, in order to relieve the load in a narrow-band terrestrial network. We show that with limited overhead, a traffic can be offloaded, leading to an increase in the user’s quality-of-experience.
