  • Constellation Design for Bit-Interleaved Coded Modulation (BICM) Systems
           in Advanced Broadcast Standards
    • Authors: Jon Barrueco;Jon Montalban;Cristina Regueiro;Manuel Vélez;Juan Luis Ordiales;Heung-Mook Kim;Sung-Ik Park;Sunhyoung Kwon;
      Pages: 603 - 614
      Abstract: This paper presents a generic methodology to optimize constellations based on their geometrical shaping for bit-interleaved coded modulation (BICM) systems. While the method can be applicable to any wireless standard design it has been tailored to two delivery scenarios typical of broadcast systems: 1) robust multimedia delivery and 2) UHDTV quality bitrate services. The design process is based on maximizing the BICM channel capacity for a given power constraint. The major contribution of this paper is a low complexity optimization algorithm for the design of optimal constellation schemes. The proposal consists of a set of initial conditions for a particle swarm optimization algorithm, and afterward, a customized post processing procedure for further improving the constellation alphabet. According to the broadcast application cases, the sizes of the constellations proposed range from 16 to 4096 symbols. The BICM channel capacities and performance of the designed constellations are compared to conventional quadrature amplitude modulation constellations for different application scenarios. The results show a significant improvement in terms of system performance and BICM channel capacities under additive white Gaussian noise and Rayleigh independently and identically distributed channel conditions.

  • Improved Bootstrap Design for Frequency-Domain Signaling Transmission
    • Authors: Yihang Huang;Dazhi He;Yin Xu;Yanfeng Wang;Wenjun Zhang;Mingmin Wang;
      Pages: 615 - 626
      Abstract: In ATSC 3.0, a bootstrap is used to enable initial synchronization and carry transmission parameter signaling. The bootstrap consists of multiple orthogonal frequency division multiplexing symbols which enables variable signaling capacity. Signaling information is conveyed by applying cyclic shift in time-domain. However, the bootstrap suffers from performance loss in the channels of strong multipath and fast time-variation. In this paper, an improved bootstrap enabling separate design of synchronization part and signaling transmission part is proposed. Zero correlation zone sequence is employed in frequency-domain (FD) for signaling transmission by cyclically shifting the sequence in FD. At the receiver, a universal signaling decoding method regardless of the synchronization part design is presented. Besides, to eliminate the performance degradation introduced by non-linear distortion of channel transfer function, signaling validation and correction operations on the previous symbol are required. Numerical simulation indicates that the proposed design achieves better signaling transmission performance than current one in some corner cases.

  • Pragmatic TCMs With General Cross-Type M-QAM Constellations
    • Authors: Sukneung Bae;Suil Kim;Junghwan Kim;
      Pages: 627 - 634
      Abstract: Recent applications of pragmatic trellis-coded modulation (TCM) to the 2k-quadrature amplitude modulation (QAM) (where k is an even integer) have been preferred to utilize the square-type constellations due to its simplicity for practical implementation. However, these schemes limit a degree of freedom in designing transceivers since the cross-type constellations cannot be used. In this paper, pragmatic TCM having cross-type 2k-QAM constellations with the odd integer k's greater than 4 are proposed. The proposed work includes details on the transceiver structures of pragmatic TCM based on the required constellation remapping rules. In addition, the approximate bit error rates (BERs) of 32 (k = 5) and 128 (k = 7)-QAM utilizing the proposed rules are analytically derived and their BER performances are evaluated by the Monte-Carlo simulation. Simulation results of comparable performances to the conventional TCM schemes confirm the validity of the proposed transceiver design and the soundness of the BER analyses for the cross-type M-QAM constellations.

  • Fast Fading Channel Estimation by Kalman Filtering and CIR Support
    • Authors: Zakia Jellali;Leïla Najjar Atallah;
      Pages: 635 - 643
      Abstract: Structured estimation of channel impulse response (CIR) is considered in orthogonal frequency division multiplexing (OFDM) systems for which the channel exhibits a sparse time-domain response. In particular, fast fading channels encountered in mobile wireless communications are envisaged. Such channels are characterized by time varying frequency selective response. This contribution exploits the much slower variation of propagation time delays, compared to propagation gains, to enhance CIR estimation. To this end, we propose a scheme that disjointly and successively tracks the delay-subspace, by Kalman filtering, then tracks the CIR structure. Contrarily to former subspace based channel response tracking, the channel order is unknown. The channel sparsity in the time-domain is accounted for by incorporating an adaptive CIR support tracking. This adaptive procedure combines the last and current OFDM blocks recovered CIR structures. To fine tune the CIR support, enhanced threshold-based CIR structure detection is applied on the recovered CIR estimate over its detected support. Finally, a structured LS estimation is processed. The proposed scheme outperforms sparsity-unaware Kalman tracking algorithm. It achieves similar performance than the best benchmark which is based on perfect CIR structure knowledge.

  • Pilot-Aided Channel Estimation Utilizing Intrinsic Interference for
           FBMC/OQAM Systems
    • Authors: Jeong-Min Choi;Youngho Oh;Hakju Lee;Jong-Soo Seo;
      Pages: 644 - 655
      Abstract: This paper proposes a novel channel estimation technique for the offset quadrature amplitude modulation based filter bank multi-carrier (FBMC/OQAM) systems. Unlike the conventional approaches, the proposed pilot signals utilize their intrinsic interference for the channel estimation, and provide an improved power efficiency compared to the conventional auxiliary pilot method. However, due to the non-whiteness of the noise components at the output of the analysis filter banks, the power gain obtained by the proposed scheme cannot be maximized. To overcome this difficulty, we propose a semiblind channel estimation by grouping the pilot signals and imposing sign ambiguities to them. Theoretical analysis shows that the proposed semiblind channel estimation remarkably improves the power efficiency of its non-semiblind version. Finally, it is demonstrated that the near optimum detection performance is achieved by the proposed scheme at a reduced complexity.

  • Toward an LTE Hybrid Unicast Broadcast Content Delivery Framework
    • Authors: Louis Christodoulou;Omar Abdul-Hameed;Ahmet M. Kondoz;
      Pages: 656 - 672
      Abstract: The era of ubiquitous access to a rich selection of interactive and high quality multimedia has begun; with it, significant challenges in data demand have been placed on mobile network technologies. Content creators and broadcasters alike have embraced the additional capabilities offered by network delivery; diversifying content offerings and providing viewers with far greater choice. Mobile broadcast services introduced as part of the long term evolution standard, that are to be further enhanced with the release of 5G, do aid in spectrally efficient delivery of popular live multimedia to many mobile devices, but, ultimately rely on all users expressing interest in the same single stream. The research presented herein explores the development of a standards aligned, multi-stream aware framework; allowing mobile network operators the efficiency gains of broadcast while continuing to offer personalized experiences to subscribers. An open source, system level simulation platform is extended to support broadcast, characterized, and validated. This is followed by the implementation of a hybrid unicast broadcast synchronization (HUBS) framework able to dynamically vary broadcast resource allocation. The HUBS framework is then further expanded to make use of scalable video content.

  • Inter-Palette Coding in Screen Content Coding
    • Authors: Weijia Zhu;Kai Zhang;Jicheng An;Han Huang;Yu-Chen Sun;Yu-Wen Huang;Shawmin Lei;
      Pages: 673 - 679
      Abstract: The joint collaborative team on video coding has been developing an emerging standard for screen content coding (SCC) as an extension of HEVC known as HEVC-SCC. Intrablock copy (IBC) and palette coding are the two powerful coding tools adopted into HEVC-SCC. In this paper, a novel coding tool named inter-palette coding is proposed, which takes the advantages of both IBC and palette coding. With the inter-palette method, a new palette copy mode COPY_INTER can be applied, which enables the index samples to copy the pixels in the prediction block fetched by IBC or motion compensation. Experimental results show that the proposed scheme can achieve 3.15% BD-rate savings under all intra conditions on typical sequences containing “text and graphics with motion” averagely, with almost no complexity penalty.

  • A Fast HEVC Encoding Method Using Depth Information of Collocated CUs and
           RD Cost Characteristics of PU Modes
    • Authors: Kuang-Han Tai;Min-Yuan Hsieh;Mei-Juan Chen;Chia-Yen Chen;Chia-Hung Yeh;
      Pages: 680 - 692
      Abstract: The latest video coding standard, high efficiency video coding (HEVC), aims to achieve better coding efficiency than the H.264/AVC standard. To improve the coding performance of HEVC, tools and structures are included that also increase the computational complexity of encoding, especially for the mode decisions in the coding unit (CU), which is a structural element in the HEVC. For each CU size, the HEVC encoder performs mode decision and motion estimation using all prediction unit (PU) types and incurs massive computational burdens. In this paper, we investigate the depth correlation between the current and the collocated CU to avoid irrelevant CU procedure and truncate some PU predictions as a result. We also investigate the relationship of the rate-distortion (RD) costs after the Merge/SKIP prediction. By analyzing different CU sizes and quantization parameters, we build a mathematical model to represent the relationship for the RD costs after the Merge/SKIP prediction with an adaptive termination of the CU procedure. In addition, the relationship of the RD costs after the Merge/SKIP prediction and 2N$boldsymbol {times }2text{N}$ mode is also explored. Search range reduction is used to further speed up our algorithm. Experimental results show that our algorithm can reduce the coding time by up to 80%, and provide average coding time savings of 46%, 45%, and 52%, for low delay B, low delay P, and random access configurations, respectively. Moreover, the proposed algorithm is able to maintain coding performance similar to HM 11.0. The proposed scheme outperforms previous work in terms of both the coding speed and the RD performance.

  • Objective Assessment of Perceptual Audio Quality Using ViSQOLAudio
    • Authors: Colm Sloan;Naomi Harte;Damien Kelly;Anil C. Kokaram;Andrew Hines;
      Pages: 693 - 705
      Abstract: Digital audio broadcasting services transmit substantial amounts of data that is encoded to minimize bandwidth whilst maximizing user quality of experience. Many large service providers continually alter codecs to improve the encoding process. Performing subjective tests to validate each codec alteration would be impractical, necessitating the use of objective perceptual audio quality models. This paper evaluates the quality scores from ViSQOLAudio, an objective perceptual audio quality model, against the quality scores of PEAQ, POLQA, and PEMO-Q on three datasets containing fullband audio encoded with a variety of codecs and bitrates. The results show that ViSQOLAudio was more accurate than all other models on two of the datasets and performed well on the third, demonstrating the utility of ViSQOLAudio for predicting the perceptual audio quality for encoded music.

  • Iterative Clipping Noise Recovery of OFDM Signals Based on Compressed
    • Authors: Lin Yang;Kun Song;Yun Ming Siu;
      Pages: 706 - 713
      Abstract: The simple method of clipping is widely used to reduce the peak-to-average power ratio of orthogonal frequency division multiplexing (OFDM) signal prior to passing it through the high power amplifier (HPA). However, clipping is a nonlinear process that causes both in-band and out-of-band distortions. Filtering the clipped OFDM signal can eliminate the out-of-band distortion but it can lead to peak regrowth. Therefore, iterative clipping and filtering have been used to both remove the out-of-band interference and suppress the regrowth of the peak power. However, the iterative process will degrade the bit error rate performance further. In this paper, we proposed a semi-analytic scheme based on compressed sensing to reconstruct the iterative clipping noise. Moreover, the proposed scheme is also applicable for reconstructing the total nonlinear distortion of a system so that the OFDM signal passes both the clipper and HPA. Simulation results show that the proposed scheme performs well and the nonlinear distortion can be recovered effectively.

  • Compressive Sensing-Based Detector Design for SM-OFDM Massive MIMO High
           Speed Train Systems
    • Authors: Bo Gong;Lin Gui;Qibo Qin;Xiang Ren;
      Pages: 714 - 726
      Abstract: In this paper, spatial modulation (SM)-orthogonal frequency division multiplexing is introduced to massive multi-input multi-output high speed train systems to reduce the complexity of the receiver. First, the mathematic model of signal detection in frequency domain is formed as a compressive sensing (CS) problem. Based on this model, a novel detector, which exploits the unique group sparsity of the signal, is proposed to improve the accuracy of the nonzero elements localization. On the basis of the channel matrix decomposition, the detector combines the CS algorithms and the iteration process together to overcome the performance deterioration brought by inter-carrier interference. Moreover, theoretical analysis about the performance gain guarantee of our proposed detector is conducted and the complexity of the proposed detector is compared with the related works. Furthermore, we also extend our proposed detector into the special scenario that the train passes the overlapped area of the adjacent two cells and receives the superimposed signal. In order to deal with the inter-cell interference, a generalized SM framework is adopted to model the signal detection. Simulation results verify that the proposed detectors have an apparent performance gain compared to the conventional CS schemes with the same complexity order.

  • Efficient Decoding of LDM Core Layer at Fixed Receivers in ATSC 3.0

      Abstract: In order to decode an enhanced layer (EL) signal for a layered-division multiplexing (LDM) system at fixed receivers in ATSC 3.0, low-density parity-check (LDPC)/BCH decoding and successive interference cancellation should be performed to eliminate the core layer (CL) signal. For a high signal-to-noise ratio environment and sufficient low injection level of the EL signal, the CL bit-interleaved coded modulation decoder can easily achieve quasi error free for the whole LDPC codeword. However, for high injection levels, there may be still many erroneous bits in the parity part even after LDPC/BCH decoding since the ATSC 3.0 LDPC codes have the characteristic of unequal error protection due to the unequal weight distributions in their parity-check matrices. Therefore, ATSC 3.0 receivers should include re-encoding module for CL LDPC codes to completely recover the CL signal for LDM system. In this paper, we propose an efficient method to reconstruct CL signal in ATSC 3.0 LDM systems, which can be realized by a modified re-encoding after LDPC decoding of the CL signal. It significantly reduces the computational complexity and worst case latency without any loss of coding performance.

  • Offset and Normalized Min-Sum Algorithms for ATSC 3.0 LDPC Decoder
    • Authors: Seho Myung;Sung-Ik Park;Kyung-Joong Kim;Jae-Young Lee;Sunhyoung Kwon;Jeongchang Kim;
      Pages: 734 - 739
      Abstract: Offset min-sum algorithm (OMSA) and normalized min-sum algorithm (NMSA) are widely used in commercial LDPC decoders due to low complexity and reasonable performance. In this paper, we provide optimized offset and scaling values for those LDPC decoders based on Advanced Television Systems Committee (ATSC) 3.0 LDPC codes. Furthermore, according to extensive computer simulations, it is shown that the performance of the OMSA and NMSA with the obtained values is close to that of sum-product algorithm, even though the NMSA-based decoder may show a serious error floor due to a channel mismatch effect. Consequently, we recommend that the ATSC 3.0 transmitters use a concatenation of BCH outer code and LDPC inner code as channel coding, considering the use of NMSA for LDPC decoder in ATSC 3.0 receivers.

           Low-Complexity H.265/HEVC Encoder”
    • Authors: Sang-hyo Park;Euee S. Jang;
      Pages: 740 - 742
      Abstract: In this paper, we provide comments on the recent paper by Pan et al. that proposed an initial search point-based motion estimation skipping (ISP-MES) method. We found some discrepancies of the proposed method and its experimental results, especially in setting the ISPs. In this paper, we clarify these issues and, as a result, provide an enhanced results from the work of Pan et al.
