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.

Low Density Parity Check Codes Constructed from Hankel Matrices

open access: yesJournal of Telecommunications and Information Technology, 2018
In this paper, a new technique for constructing low density parity check codes based on the Hankel matrix and circulant permutation matrices is proposed. The new codes are exempt of any cycle of length 4.

Enhanced belief propagation decoding of polar codes by adapting the parity-check matrix

open access: yesEURASIP Journal on Wireless Communications and Networking, 2017
Though the performance of belief propagation (BP) decoder for polar codes is comparable with the successive cancellation (SC) decoder, it has significant performance gap when compared with the improved SC decoders, such as SC list (SCL) decoding. In this

Reconstruction of sparse check matrix for LDPC at high bit error rate

open access: yesTongxin xuebao, 2021
In order to reconstruct the sparse check matrix of LDPC, a new algorithm which could directly reconstruct the LDPC was proposed.Firstly, according to the principle of the traditional reconstruction algorithm, the defects of the traditional algorithm and ...

LDPC codes from the Hermitian curve [PDF]

open access: yes, 2007
In this paper, we study the code C which has as parity check matrix H the incidence matrix of the design of the Hermitian curve and its (q + 1)-secants. This code is known to have good performance with an iterative decoding algorithm, as shown by Johnson

Optimization of the parity-check matrix density in QC-LDPC code-based McEliece cryptosystems [PDF]

open access: yesInternational Conference on Intelligent Cloud Computing, 2013
Low-density parity-check (LDPC) codes are one of the most promising families of codes to replace the Goppa codes originally used in the McEliece cryptosystem.

A Construction of Optimal $(r,\delta)$ -Locally Recoverable Codes

open access: yesIEEE Access, 2019
Locally recoverable codes (LRCs) play a significant role in distributed and cloud storage systems. The key ingredient for constructing such optimal LRCs is to characterize the parity-check matrix for LRCs.
