Multilevel structured low-density parity-check codes [PDF]
, 2008 Low-Density Parity-Check (LDPC) codes are typically characterized by a relatively high-complexity description, since a considerable amount of memory is required in order to store their code description, which can be represented either by the connections ...

BIT ERROR OPTIMIZATION OF CODED OFDM SYSTEM OVER RAYLEIGH FADING CHANNEL [PDF]
Journal of Engineering and Sustainable Development, 2019 Low Density Parity-Check (LDPC) codes are one of the hottest topics in coding theory today. This code invented in the early 1960's, and it having an amazing comeback in the last few years.

Augmented decoders for LDPC codes [PDF]
EURASIP Journal on Wireless Communications and Networking, 2018 Abstract The performance of a belief propagation decoder for low-density parity-check codes is limited by the presence of trapping sets in the code’s graph. This leads to an error floor at higher signal-to-noise ratios. We propose the use of an augmented decoder which operates by iteratively decoding on a set of graphs which have a subset of repeated ...

On the Stopping Distance of SA-LDPC Codes by Transversal Designs
IEEE Access, 2018 In this paper, we analyze the size of the smallest stopping set (called the stopping distance) for the parity-check matrix of a superposed array low-density parity-check (SA-LDPC) code for column weights 3 and 4 by using the transversal design (TD ...

Differentially Encoded LDPC Codes—Part II: General Case and Code Optimization
EURASIP Journal on Wireless Communications and Networking, 2008 This two-part series of papers studies the theory and practice of differentially encoded low-density parity-check (DE-LDPC) codes, especially in the context of noncoherent detection. Part I showed that a special class of DE-LDPC codes, product accumulate

COMPARATIVE ANALYSIS OF LDPC AND BCH CODES ERROR-CORRECTING CAPABILITIES
Information and Telecommunication Sciences, 2014 The error-correcting capabilities of regular LDPC (Low Density Parity Check) codes and BCH (Bose-Chaudhuri-Hocquenguem) codes are examined. The qualitative analysis and the quantitative assessment of error-correcting abilities are performed for LDPC ...
