Multilevel structured low-density parity-check codes [PDF]

open access: yes, 2008
Low-Density Parity-Check (LDPC) codes are typically characterized by a relatively high-complexity description, since a considerable amount of memory is required in order to store their code description, which can be represented either by the connections ...

Non-binary protograph low-density parity-check codes for space communications [PDF]

open access: yes, 2012
Protograph-based non-binary low-density parity-check (LDPC) codes with ultra-sparse parity-check matrices are compared with binary LDPC and turbo codes (TCs) from space communication standards.

A construction of the high-rate regular quasi-cyclic LDPC codes

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
In this paper, a scheme to construct the high-rate regular quasi-cyclic low-density parity-check (QC-LDPC) codes is developed based on the finite geometry low-density parity-check (LDPC) codes.

Quasi-cyclic Generalized LDPC codes with low error floors [PDF]

open access: yes, 2008
In this paper, a novel methodology for designing structured generalized LDPC (G-LDPC) codes is presented. The proposed design results in quasi-cyclic G-LDPC codes for which efficient encoding is feasible through shift-register-based circuits.

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.

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.
