Blind recognition of sparse parity‐check matrices of low‐density parity‐check codes in the presence of noise

open access: yesIET Communications, 2023
This paper studies the blind recognition method of the sparse parity‐check matrices of low‐density parity‐check codes in noncooperative communication, which is critical to the reverse analysis of communication protocols using LDPC codes.

Genetic Optimization of LDPC Codes to Improve the Correction of Burst Errors [PDF]

open access: yesEPJ Web of Conferences, 2020
Error correction plays a crucial role when transmitting data from the source to the destination through a noisy channel. It has found many applications in television broadcasting services, data transmission in radiation harsh environment (e. g.

Nonbinary Spatially-Coupled LDPC Codes on the Binary Erasure Channel [PDF]

open access: yes, 2012
We analyze the asymptotic performance of nonbinary spatially-coupled low-density parity-check (SC-LDPC) codes built on the general linear group, when the transmission takes place over the binary erasure channel.

CONSTRUCTION OF REGULAR LDPC LIKE CODES BASED ON FULL RANK CODES AND THEIR ITERATIVE DECODING USING A PARITY CHECK TREE [PDF]

open access: yesICTACT Journal on Communication Technology, 2011
Low density parity check (LDPC) codes are capacity-approaching codes, which means that practical constructions exist that allow the noise threshold to be set very close to the theoretical Shannon limit for a memory less channel.

Deriving Good LDPC Convolutional Codes from LDPC Block Codes [PDF]

open access: yes, 2010
Low-density parity-check (LDPC) convolutional codes are capable of achieving excellent performance with low encoding and decoding complexity. In this paper we discuss several graph-cover-based methods for deriving families of time-invariant and time ...
