摘要

本文提出了一种设计低密度奇偶校验码奇偶矩阵的简单方法。根据其使用情况，等差序列是不存在周期4的高速率码的理想选择。该设计适用于阵列码、修改阵列码和准循环码。经过调查，设计的代码与更复杂的设计矩阵相比具有相似的BER-SNR性能。

A simple algorithm for a high code rate LDPC parity matrix design

This paper presents a simple method in designing a parity matrix of low density parity check codes. According to its use the use of arithmetic sequence is ideal for high rate code with no existing of cycle 4. The design is applicable to array code, modified array code, and quasi cyclic code. Upon the investigation, the designed code has delivered a similar BER-SNR performance when compared with that of more complicate designed matrices.
