摘要 简述了LDPC码的研究现状及编码方法。在此基础上分析了目前常用的编码实现方式,并针对一类准循环LDPC码的特点,提出一种更简洁的快速编码算法及设计实现思路。 Firstly, this paper introduces the study status and encoding methods of LDPC codes, and then analyzes some general encoding methods. Finally, as to the characteristics for a set of quasi-cyclic LDPC codes, a simpler encoding method is put forward, meanwhile the hardware designing method is also put forward.
