An FPGA Implementation of-Regular Low-Density Parity-Check Code Decoder

open access: yesEURASIP Journal on Advances in Signal Processing, 2003
Because of their excellent error-correcting performance, low-density parity-check (LDPC) codes have recently attracted a lot of attention. In this paper, we are interested in the practical LDPC code decoder hardware implementations.

Design and performance of a novel low-density parity-check code for distributed video coding

open access: yes2008 15th IEEE International Conference on Image Processing, 2008
Low-density parity-check (LDPC) codes are nowadays one of the hottest topics in coding theory, notably due to their advantages in terms of bit error rate performance and low complexity.

An Efficient Method to Construct Parity-Check Matrices for Recursively Encoding Spatially Coupled LDPC Codes †

open access: yesEntropy, 2016
Spatially coupled low-density parity-check (LDPC) codes have attracted considerable attention due to their promising performance. Recursive encoding of the codes with low delay and low complexity has been proposed in the literature but with constraints ...

Non Binary Low Density Parity Check Codes Decoding Over Galois Field [PDF]

open access: yes, 2015
Conventional LDPC codes have a low decoding complexity but may have high encoding complexity. The encoding complexity is typically of the order O(n2)[5]. Also high storage space may be required to explicitly store the generator matrix. For long blocknbsp

The Effect of Saturation on Belief Propagation Decoding of LDPC Codes

open access: yes, 2014
We consider the effect of LLR saturation on belief propagation decoding of low-density parity-check codes. Saturation occurs universally in practice and is known to have a significant effect on error floor performance.

Weight Distribution for Non-binary Cluster LDPC Code Ensemble [PDF]

open access: yes, 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 ...

Research on LDPC Coding for Free Space Optical Communication with Modified Bessel-Gaussian Beams Based on K-distribution

open access: yesMATEC Web of Conferences, 2018
We investigate the performance of low-density parity-check (LDPC) coding for free space optical communication (FSO) with modified Bessel-Gaussian (MBG) beams based on K-distribution.

Construction of Short-length High-rates Ldpc Codes Using Difference Families [PDF]

open access: yes, 2007
Low-density parity-check (LDPC) code is linear-block error-correcting code defined by sparse parity-check matrix. It isdecoded using the massage-passing algorithm, and in many cases, capable of outperforming turbo code.
