摘要

本文描述了基于部分单元存储器(P)UM码的低密度奇偶校验(LDPC)分组码集成。研究了不同组成LDPC码参数情况下接收集成的译码性能。给出了一种迭代“信念传播”(和积)译码算法的编码结构的仿真结果，该算法应用于具有加性高斯白噪声和BPSK调制的二进制信道传输码字的情况。

Low-Density Parity-Check codes based on Partial Unit Memory codes

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.
