A Decoding Algorithm for LDPC Codes Over Erasure Channels with Sporadic Errors [PDF]

, 2010
none4An efficient decoding algorithm for low-density parity-check (LDPC) codes on erasure channels with sporadic errors (i.e., binary error-and-erasure channels with error probability much smaller than the erasure probability) is proposed and its ...

FPGA implementation of low density parity-check (LDPC) coded recording channels [PDF]

, 2019
Low Density Parity-Check (LDPC) codes have received lots of attention during the past decade due to their near Shannon-limit performance and decoding at very high rates. However, several issues have been raised in the research work with an aim to achieve the practical implementation of the LDPC codes. The first major issue is the performance evaluation

Threshold Analysis of Non-Binary Spatially-Coupled LDPC Codes with Windowed Decoding

, 2014
In this paper we study the iterative decoding threshold performance of non-binary spatially-coupled low-density parity-check (NB-SC-LDPC) code ensembles for both the binary erasure channel (BEC) and the binary-input additive white Gaussian noise channel (

5G‐coded fluid antenna multiple access over block fading channels

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This letter investigates the use of 5G New Radio (NR) Modulation Coding Scheme (MCS) for FAMA systems to improve its connectivity over block fading channels. In particular, we propose an iterative decoding receiver with iterative interference covariance estimation, designed explicitly for slow fading channels.

Efficient LDPC Code Design based on Genetic Algorithm for IoT Applications

EAI Endorsed Transactions on Industrial Networks and Intelligent Systems
In this paper, we propose a low-density parity check (LDPC) code design scheme that improves the performance of the existing genetic algorithm-based LDPC scheme. In particular, we enhance the performance of the LDPC code by removing the girth-4 property

New decoding scheme for LDPC codes based on simple product code structure

, 2012
In this paper, a new decoding scheme for low-density parity-check (LDPC) codes using the concept of simple product code structure is proposed based on combining two independently received soft-decision data for the same codeword.

A Non‐Binary Dual Cascade Polar Codes Construction and Low‐Complexity SCL Decoding

Electronics Letters, Volume 61, Issue 1, January/December 2025.
First, we design an error‐correction approach including two cascade non‐binary polar coding (NB‐CPolar) structures and a cyclic redundancy check (CRC) code. Second, we propose a low‐complexity decoding algorithm based on non‐binary successive cancellation list (NB‐LSCL) decoding.
