“…When t n transmissions occur for a single transmitted signal vector, the proposed receiver scheme [10] first concatenates the received signal vectors, the noise vectors, and the corresponding channel matrices as follows, respectively, y = [(y (1) ) T (y (2) ) T · · · (y (t n ) ) T ] T , n = [(n (1) ) T (n (2) ) T · · · (n (t n ) ) T ] T ,…”

“…To address these problems, an HARQ system is proposed, which incorporates both an ARQ system and an FEC code. HARQ, including the Chase combining (HARQ-CC) [1] and incremental redundancy (HARQ-IR) [2], can contribute to more effective use of the available resources, and it has been involved in the latest-generation wireless systems such as IEEE 802.16e [3] and 3GPP-LTE [4].…”

This paper proposes a novel receiver scheme for multiple-input multiple-output (MIMO) systems with hybrid automatic-retransmission-request (HARQ) mechanism. The scheme is based upon Dempster-Shafer evidence theory (DST), and improves the decoding performance by characterizing the uncertainty contained in the received signals. In addition, the new scheme can further counteract the uncertainty of the soft decisions by combining multiple soft information sources. Furthermore, it can make full use of the received signals and performs especially well when the transmitted signal is nonuniformly distributed, as compared with the maximum-likelihood (ML) approach. This paper analyzes the proposed scheme and its counterparts in terms of two key design factors: decoding performance and the complexity imposed. Simulation results under IEEE 802.16e setting with UMTS channel model demonstrate that the proposed receiver scheme with low complexity outperforms the ML approach, and reaps much more performance gain with only moderate complexity increase over the other suboptimal receiver schemes. The simulations show a good agreement with the performance analysis of the combining schemes.Keywords Basic probability assignment (BPA) · Dempster-Shafer evidence theory (DST) · Hybrid automatic-retransmission-request (HARQ) · Multiple-input multiple-output (MIMO) · Packet combining A part of this article was presented at GLOBECOM'09.J.

“…The system devised by Lin and Yu was developed for satellite channels. Type-II systems based on RS and RM codes were later developed by Pursley and Sandberg [95] and by Wicker and Bartz [96], [97], and similar systems which utilize RCPC codes were introduced by Hagenauer [60].…”

Abstract-An overview of the many practical applications of channel coding theory in the past 50 years is presented. The following application areas are included: deep space communication, satellite communication, data transmission, data storage, mobile communication, file transfer, and digital audio/video transmission. Examples, both historical and current, are given that typify the different approaches used in each application area. Although no attempt is made to be comprehensive in our coverage, the examples chosen clearly illustrate the richness, variety, and importance of error-control coding methods in modern digital applications.

“…A commonly used technique to mitigate the effects of the time-varying channels and achieve flexible and adaptive channel coding are rate-compatible (RC) codes. RC codes are defined as a family of codes where the bit stream of a low redundancy channel code is embedded in the bit stream of a high redundancy channel code [1][2][3][4][5]. Therefore, the encoder/decoder design complexity is greatly reduced since all the codes in the family can be encoded and decoded using only the lowest rate encoder/decoder pair [2].…”

A low-complexity algorithm for the design of efficiently-encodable rate-compatible (RC) low-density parity-check (LDPC) codes by deterministically extending an irregular repeat-accumulate (IRA) is introduced. The extending structure is based on circulants shifted according a truncated Vandermonde matrix (VM) and therefore termed as "extended VM" (eVM). The novel extending algorithm is significantly less computationally complex than other known similar methods since it does not require any optimization of the extending profile or any post-construction girth conditioning. To improve the codes' properties and correcting capabilities in low code rate applications, the optimal proportions of degree-1 and degree-2 parity bits for the extended nodes are investigated and, in contrast to existing deterministic extending approaches for RC-IRA codes, an extending increment step equal to half the information block length is chosen. Various bit error rate (BER) and frame error rate (FER) have been obtained for different code rates, R, and information block length k 0 = 512 and 1024 bits considering an additive white Gaussian noise (AWGN) channel. The results have demonstrated that the proposed eVM RC-LDPC codes, despite their very simple structure and very low computational complexity, exhibit excellent performance only slightly inferior to both dedicated IRA and previously known RC-IRA codes for different data block sizes.
