Abstract :
In this paper we describe ensemble of Low-Density Parity-Check (LDPC) block codes based on Partial Unit Memory (P)UM codes. We study a decoding performance of received ensemble in the case of different parameters of constituent LDPC codes. The results of simulation of 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 and BPSK modulation, are presented.
