| 摘 要： | LDPC码是一类线性分组码,具有硬件可实现的译码器,在很多数据传输和数据存储信道上都表现出逼近信道容量的性能。其中QC结构是一种用于硬件实现的理想结构,QC-LDPC码的编码能够利用线性移位寄存器来进行有效地编码。但是由于QC-LDPC码中必然环的存在,极大的限制了传统QC-LDPC码的应用价值。本文将介绍一类由零矩阵和相同阶的仿射置换矩阵构成的LDPC码,并通过仿真将QC-LDPC码和APM-LDPC码的性能进行比较。

| Abstract: | LDPC code is a kind of linear block code,with hardware realizable decoder,the performance in a lot of data transmission and data storage channel close to the capacity of the channel.QC structure is an ideal structure for hardware implementation.QC-LDPC code can be effectively coded by using linear shift register.However,the existence of inevitable loop in qc-ldpc code greatly limits the application value of traditional qc-ldpc code.This paper introduces a class of LDPC codes composed of zero matrix and affine permutation matrix of the same order,and compares the performance of qc-ldpc codes and apm-ldpc codes through simulation. |
