Evaluation of Low Density Parity Check Codes Over Various Channel Types [PDF]
Engineering and Technology Journal, 2011 Low density parity check (LDPC) codes are one of the best error correcting codes in today’s coding world and are known to approach the Shannon limit. As with all other channel coding schemes, LDPC codes add redundancy to the uncoded input data to make it

Low-Density Parity-Check Codes
IEICE ESS Fundamentals Review, 2021 Low Density Parity Check codes, LDPCs for short, are a family of codes which have shown near optimal error-correcting capabilites. They were proposed in 1963 by Robert Gallager in his PhD thesis. While he proved that probabilistic constructions of random LDPCs gave asymptotically good linear codes, they were largely abandoned due to the lack of ...

Spatially Coupled Generalized Low-Density Parity-Check Codes Over Class-A Impulsive Noise Channels
IEEE Access, 2019 In this paper, a class of spatially coupled generalized low-density parity-check (SC-GLDPC) codes with minimum coupling width is introduced to mitigate the Class-A impulsive noise. Codes with minimum coupling width are beneficial to simple code structure,

Adaptive Cut Generation Algorithm for Improved Linear Programming Decoding of Binary Linear Codes [PDF]
, 2012 Linear programming (LP) decoding approximates maximum-likelihood (ML) decoding of a linear block code by relaxing the equivalent ML integer programming (IP) problem into a more easily solved LP problem.

Carrier phase recovery of LDPC-coded systems based on the likelihood difference algorithm
EURASIP Journal on Advances in Signal Processing, 2023 The problem of blind phase offset recovery of low density parity-check (LDPC)-coded systems is considered in this paper. We propose a new algorithm of phase offset estimation that involves the computation and maximization of a likelihood difference (LD ...

Double-Layer Low-Density Parity-Check Codes over Multiple-Input Multiple-Output Channels
International Journal of Antennas and Propagation, 2012 We introduce a double-layer code based on the combination of a low-density parity-check (LDPC) code with the multiple-input multiple-output (MIMO) system, where the decoding can be done in both inner-iteration and outer-iteration manners.

Weight Distribution for Non-binary Cluster LDPC Code Ensemble [PDF]
, 2013 In this paper, we derive the average weight distributions for the irregular non-binary cluster low-density parity-check (LDPC) code ensembles. Moreover, we give the exponential growth rate of the average weight distribution in the limit of large code ...

Constructing Grith Eight GC-LDPC Codes Based on the GCD FLRM Matrix with a New Lower Bound
Sensors, 2022 By connecting multiple short, local low-density parity-check (LDPC) codes with a global parity check, the globally coupled (GC) LDPC code can attain high performances with low complexities.
