  • Information-Theoretic Analysis and Performance Evaluation of Optimal
           Demappers for Multi-Layer Broadcast Systems
    • Authors: Eduardo Garro;Jordi Joan Gimenez;Peter Klenner;David Gomez-Barquero;
      Pages: 781 - 790
      Abstract: Multi-layer broadcast systems distribute services across time and frequency domain by means of power-division multiplexing. Successive interference cancelation is required, in general, in order to extract the content of all services. For a low-complexity implementation, the receiver can obtain the strongest (top-layer) signal assuming underlying signals to behave like thermal noise. The thermal noise assumption may not be valid under certain conditions and a more accurate characterization of the interference could bring improved performance. This paper analyzes the validity of the noise-like assumption considering the power ratio between signals and the required carrier-to-noise ratio for error-free reception. The main contribution of the paper is the proposal of a demapping algorithm that exploits the knowledge of the constellation of underlying signals. Generalized mutual information, performance evaluation, and complexity analysis are provided with the additive white Gaussian noise-like assumptions and with the proposed alternative in order to assess the potential performance improvements that can be achieved.

  • An Optimized Hybrid Unicast/Multicast Adaptive Video Streaming Scheme Over
           MBMS-Enabled Wireless Networks
    • Authors: Jia Guo;Xiangyang Gong;Jie Liang;Wendong Wang;Xirong Que;
      Pages: 791 - 802
      Abstract: Mobile multimedia services have been increasingly popular. However, radio resources are limited. The quality of experience of all users in wireless networks can be enriched by resource allocation, which is affected by many factors in current wireless networks. In this paper, we focus on a hybrid unicast-multicast (HUM) video streaming scheme, and develop an adaptive resource allocation framework for HUM by combining adaptive cooperative transmission and base station handoff. The optimization problem is formulated as a multi-dimensional, complexity-constrained nonlinear NP-hard problem. To solve the problem, a greedy algorithm and a genetic algorithm are proposed. Simulation results demonstrate that our scheme has superior performance than other transmission methods in the literature. The genetic algorithm has better performance, but the greedy algorithm can maintain better balance between performance and resource consumption.

  • Uniformly Projected RCQD QAM: A Low-Complexity Signal Space Diversity
           Solution Over Fading Channels With or Without Erasures
    • Authors: Tarak Arbi;Benoît Geller;Jianxiao Yang;Charbel Abdel Nour;Olivier Rioul;
      Pages: 803 - 815
      Abstract: Rotated and cyclic Q-delayed (RCQD) quadrature amplitude modulation provides signal space diversity and thus improves system performance over fading channels. However, previously published RCQD solutions were designed without fully considering the high demodulation complexity which prohibits wider applications. In this paper, a complete solution is proposed to reduce complexity for both the modulator and the demodulator. This solution uses a series of rotation angles ${alpha =}$ arctan( $1/{sqrt {M}}$ ) which bring many interesting properties to the RCQD signals. A simplified sphere demapping algorithm is derived for fading channels with and without erasure events. In contrast to the sphere-decoder used for multiple input multiple output detection, the radius of the proposed sphere-demapper involves an exact amount of constellation points, thereby ensuring to perform the soft demapping operation successfully. Moreover, when either the in-phase ( ${I}$ ) or the quadrature component ( ${Q}$ ) is erased, the proposed demapping algorithm performs as well as the full-complexity max-log algorithm, with a reduced complexity. Compared to the solution currently used in DVB-T2, the proposed method reduces tremendously the computational complexity while still achieving similar performance over fading channels and even better performance over fading erasure channels.

  • Progressive Matrix Growth Algorithm for Constructing Rate-Compatible
           Length-Scalable Raptor-Like Quasi-Cyclic LDPC Codes
    • Authors: Yushu Zhang;Kewu Peng;Zhangmei Chen;Jian Song;
      Pages: 816 - 829
      Abstract: With the worldwide deployment and rapid development of digital television terrestrial broadcasting (DTTB) systems, the demands of diversified multimedia services from the fixed/mobile receptions increase significantly. To satisfy the various requirements of quality of service, the forward error correction codes with multiple code rates and lengths become a trend for DTTB standards. In this paper, rate-compatible length-scalable raptor-like quasi-cyclic low density parity check (RL-QC-LDPC) codes are proposed for future DTTB systems, where a wide range of code rates and information/parity block lengths can be obtained with low implementation complexity. A low-complexity construction method, called progressive matrix growth (PMG), is also proposed for such kind of RL-QC-LDPC codes. Unlike conventional construction methods, PMG performs 2-D progressive extension of both information variable nodes and check nodes with limited computational complexity and memory resources. Based on the performance prediction provided by the tool of multi-edge type density evolution, several code families are constructed with PMG as examples, and careful discussions on design parameters are given. The numerical results show that the average gaps of SNR threshold to Shannon limit of binary-input additive white Gaussian noise channel are only 0.41~0.44 dB for the code families with information-bit puncturing.

  • Blind Reconstruction of Reed-Solomon Encoder and Interleavers Over Noisy
           Environment
    • Authors: Swaminathan R;A. S. Madhukumar;Guohua Wang;Ting Shang Kee;
      Pages: 830 - 845
      Abstract: Blind estimation of code and interleaver parameters is useful in smart storage systems and ubiquitous communication applications such as adaptive modulation and coding, reconfigurable radio systems, non-cooperative radio systems, etc. In this paper, we analyze Reed-Solomon (RS) encoded data stream and propose blind estimation algorithms to identify RS code parameters. We also provide algorithms to estimate block interleaver parameters from RS coded and block interleaved data stream. In addition, synchronization compensation through appropriate bit/symbol positioning is integrated with the proposed code and interleaver parameter estimation algorithms. Simulation results validating the proposed algorithms are given for various test cases involving both erroneous and non-erroneous scenarios. Moreover, the accuracy of estimation of RS code and block interleaver parameters are also given with detailed inferences for different modulation schemes, codeword length, and code dimension values. It has been inferred that the accuracy of parameter estimation improves with decrease in code dimension and codeword length values of RS codes. Further, the accuracy of estimation of lower modulation order schemes is better when compared to higher modulation order schemes as expected. It has also been noted that the proposed code and interleaver parameter estimation algorithms for noisy environment consistently outperform the algorithms proposed in the prior works.

  • Subband CQI Feedback-Based Multicast Resource Allocation in MIMO-OFDMA
           Networks
    • Authors: Alejandro De La Fuente;Guillem Femenias;Felip Riera-Palou;Ana García Armada;
      Pages: 846 - 864
      Abstract: Multicast transmission is one of the key enablers toward a more spectral- and energy-efficient distribution of multimedia content in current and envisaged cellular networks. In order to ensure that all users in a multicast group are able to correctly decode the received data, most multicast techniques adopt rather conservative strategies that select a very robust modulation and coding scheme (MCS) whose characteristics are determined by the propagation conditions experienced by the worst user in the group. Obviously, this robustness comes at the prize of a low spectral efficiency. Moreover, in the specific context of wideband communication systems, the selection of the multicast MCS has often relied on the use of wideband channel quality indicators (CQIs) providing rather imprecise information regarding the potential capacity of the multicast channel. Only recently has the per-subband CQI been used to improve the spectral efficiency of the system without compromising the link robustness. However, most subband-CQI multicast schemes proposed so far rely on overpessimistic assumptions that preclude the achievement of high data rates. In this paper, novel subband CQI-based multicast strategies are proposed that, relying on the selection of more spectrally efficient transmission modes, lead to increased data rates while still being able to fulfill prescribed quality of service metrics. To this end, a constrained optimization problem is posed that seeks to maximize the data rate of the whole multicast group while ensuring that the average block error rate for all users remains below a threshold and that a minimum data rate is guaranteed for all users in the group.

  • Saliency-Guided Complexity Control for HEVC Decoding
    • Authors: Ren Yang;Mai Xu;Zulin Wang;Yiping Duan;Xiaoming Tao;
      Pages: 865 - 882
      Abstract: The latest High Efficiency Video Coding (HEVC) standard significantly improves coding efficiency over its previous video coding standards. The expense of such improvement is enormous computational complexity, from both encoding and decoding sides. Since computational capability and power capacity are diverse across portable devices, it is necessary to reduce decoding complexity to a target with tolerable quality loss, so called complexity control. This paper proposes a saliency-guided complexity control (SGCC) approach for HEVC decoding, which reduces the decoding complexity to the target with minimal perceptual quality loss. First, we establish the SGCC formulation to minimize perceptual quality loss at the constraint on reduced decoding complexity, which is achieved via disabling deblocking filter (DF) and simplifying motion compensation (MC) of some non-salient coding tree units (CTUs). One important component in this formulation is the modeled relationship between decoding complexity reduction and DF disabling/MC simplification, which determines the control accuracy of our approach. Another component is the modeled relationship between quality loss and DF disabling/MC simplification, responsible for optimizing perceptual quality. By solving the SGCC formulation for a given target complexity, we can obtain the DF and MC settings of each CTU, and then decoding complexity can be reduced to the target. Finally, the experimental results validate the effectiveness of our SGCC approach, from the aspects of control performance, complexity-distortion performance, and fluctuation of quality loss and subjective quality.

  • Quasi-Optimal Tone Reservation PAPR Reduction Algorithm for Next
           Generation Broadcasting Systems: A Performance/Complexity/Latency Tradeoff
           With Testbed Implementation
    • Authors: S. S. Krishna Chaitanya Bulusu;Matthieu Crussière;Jean-François Hélard;Ralph Mounzer;Youssef Nasser;Olivier Rousset;Alain Untersee;
      Pages: 883 - 899
      Abstract: High peak-to-average power ratio (PAPR) of the transmitted signal is a serious issue in multicarrier communication systems, such as second generation terrestrial digital video broadcasting (DVB-T2) systems. These large fluctuations prevent feeding the high power amplifier at an operating point near its non-linear saturation region thereby lowering its power efficiency. In recent years, tone reservation (TR) PAPR reduction techniques have been deeply studied and included in the DVB-T2 and the American digital video broadcasting (ATSC 3.0) specifications. It is based on a gradient iterative approach where, at each iteration, a predefined kernel is used to reduce one peak in time domain. In this paper, a novel TR PAPR reduction technique namely individual carrier allocation for multiple peaks (ICMPs) that is based on a new kernel signal is proposed. This algorithm, compatible with the DVB-T2 standard, offers better performance than the gradient-based DVB-T2 algorithm but suffers with increased complexity for higher modes of DVB-T2 and ATSC 3.0 as the number of required iterations is equal to the number of reserved tones. To overcome this issue, we propose an improved ICMP technique, called grouped ICMP defined with this new kernel. The main principle of this new algorithm consists in dividing the reserved tones into $G$ groups. This highly reduces the number of iterations, now equal to the number of groups, and thereby the latency. An in-depth performance analysis has been done by implementing our algorithm on a testbed platform with real power amplifiers. Both the simulation and experimental results demonstrated that the proposed PAPR reduction algorithm offers very good performance/complexity/latency tradeoff.

  • Compander Design for OFDM PAPR Reduction Using Optimal Perturbation of
           Piecewise Linear Segments
    • Authors: Stephen P. DelMarco;
      Pages: 900 - 908
      Abstract: In this paper, we develop an optimal perturbation approach to design companders to mitigate the peak-to-average power ratio problem experienced by orthogonal frequency division multiplexing (OFDM) signals. Specifically, we generalize single-linear component design approaches, which modify the Rayleigh-distributed OFDM signal amplitude tail, to use of multiple contiguous piecewise linear components. The new compander design approach defines and solves a constrained optimization problem to optimally perturb a given proposed multicomponent piecewise linear segment set to meet the power and probability density function constraints. The use of multiple piecewise linear components provides greater design flexibility to meet the constraints, thus providing solutions for pairs of inflection points and cutoff values where more rigidly designed companders fail to exist. We present examples of compander design, and demonstrate compander performance through numerical simulation. The new compander design approach can generate companders that offer performance improvements over current companders.

  • Spectral Efficiency Analysis for Spatial Modulation Aided Layered Division
           Multiplexing Systems With Gaussian and Finite Alphabet Inputs
    • Authors: Xuesi Wang;Jintao Wang;Longzhuang He;Jian Song;
      Pages: 909 - 914
      Abstract: In this paper, we introduce spatial modulation (SM) in the layered division multiplexing (LDM) system for digital TV scenarios. To analyze the achievable spectral efficiency (SE) performance of the proposed SM-LDM system, we calculate its mutual information (MI) through the Monte Carlo method. Considering both Gaussian and finite alphabet inputs, we derive the MI’s computational-efficient lower bounds as well as their asymptotic values. Simulation results confirm both the advantages and our SE analysis of the proposed SM-LDM system.

  • Multicasting in Next-Generation Software-Defined Heterogeneous Wireless
           Networks
    • Authors: Janfizza Bukhari;Wonyong Yoon;
      Pages: 915 - 921
      Abstract: Multicasting is an efficient mechanism to disseminate popular multimedia content to multiple interested third generation partnership project (3GPP) cellular users. To further enhance the multicast cellular capacity, non-3GPP WLAN networks can be leveraged to relieve the load of the 3GPP cellular networks. In this paper, we propose the distributed procedure of de-touring the multicast traffic to WLAN in the current LTE and WLAN heterogeneous network architecture. We also propose promising software-defined networking (SDN)-based centralized approach that facilitates multicast content dissemination, bringing efficiency and flexibility to the network. We analyze both the distributed and centralized approaches based on the multicast content popularity. Our analysis reveals that the SDN-based approach in heterogeneous cellular communication and multicasting brings significant radio resource savings. We also conduct packet-level simulation with a real SDN controller and smartphones to confirm the feasibility of the proposed SDN-based approach.

  • Cost-Based Search Ordering for Rate-Constrained Motion Estimation Applied
           to HEVC
    • Authors: Luc Trudeau;Stéphane Coulombe;Christian Desrosiers;
      Pages: 922 - 932
      Abstract: In the context of motion estimation for video coding, combining a successive elimination algorithm (SEA) with a motion estimation algorithm reduces the number of computed cost functions without impact on rate or distortion. The SEAs use the sum of absolute differences to eliminate motion vector candidates in the search area that cannot improve the current minimum. The novelty in this paper is that instead of relying on a static geometric pattern (i.e., like a spiral), we proposed a dynamic algorithm that creates a cost-based search orderings. A dynamic cost-based search ordering not only improves elimination but also allows for early termination which removes, on average, 61% of the block-matching loop iterations performed by the rate-constrained successive elimination algorithm (RCSEA). Our experiments show that the proposed solution is 5 times faster than the high efficiency video coding (HEVC) HM encoder software in full search mode with a 0.02% impact on BD-Rate. This is twice the speed of the HEVC HM software encoder using only the RCSEA.
