Comparison of Various Constructions of Binary LDPC Codes Based on Permutation Matrices

摘要

Ensembles of low-density parity check codes based on permutation matrices are considered. Algorithms for generation of check matrices of such codes are proposed. The results of simulation of the obtained code constructions for an iterative belief propagation (sum-product) decoding algorithm applied in the case of transmission of a code word via a binary channel with an additive Gaussian white noise are presented.
