Finite Length Analysis of Low-Density Parity-Check Codes on Impulsive Noise Channels
Low-density parity-check (LDPC) codes with very long block lengths are well known for their powerful error correction, but it is not always desirable to employ long codes in communication systems, where latency is a serious issue, such as voice and video

Here, a multi‐user signal iterative detection and decoding scheme named LBEP based on block expectation propagation (BEP) is proposed for LDPC‐coded two‐phase unsourced random access (URA) scheme. In the iteratively process, the approximation of matrix inversion is used to facilitate expectation propagation (EP). The numerical results show that, in the

Design of LDPC code for uncorrelated Rayleigh fading channel using modified outage probability
In this paper, we propose a new design metric called modified outage probability (MOP) for protograph-based low-density parity-check (LDPC) codes over the uncorrelated Rayleigh fading channel.

Design of rate-compatible LDPC codes based on uniform shortening distribution
Information shortening is a methodology to construct rate-compatible codes. Recently, LDPC codes have been shown that uniform shortening distribution is a criterion to achieve excellent performance.

Protograph EXIT Analysis over Block Fading Channels with Application to Relays
An accurate extrinsic information transfer (EXIT) analysis is developed for protograph low-density parity-check (LDPC) codes over the block fading channel (BFC). The analysis is thus exploited for analyzing the behavior of distributed protograph LDPC

Design of low-density parity-check codes: An overview
This article provides an overview of the conflicting design tradeoffs of low-density parity-check (LDPC) codes and thus advocates a more holistic approach to their design for wireless channels.

Short Low-Rate Non-Binary Turbo Codes
A serial concatenation of an outer non-binary turbo code with different inner binary codes is introduced and analyzed. The turbo code is based on memory-1 time-variant recursive convolutional codes over high order fields.

FNT-based reed-solomon erasure codes [PDF]
This paper presents a new construction of Maximum-Distance Separable (MDS) Reed-Solomon erasure codes based on Fermat Number Transform (FNT). Thanks to FNT, these codes support practical coding and decoding algorithms with complexity O(n log n), where n ...
