一种新的LDPC译码算法及其硬件实现

A New LDPC Decoder Algorithm and It′s Hardware Implementation

介绍了LDPC编译码技术,提出了分层修正最小和算法并对该算法进行了定点仿真和硬件实现。仿真结果和硬件实现表明,该算法性能优良并能降低迭代次数以提高吞吐量。

In this paper, the technique of LDPC is introduced. And a new Layered Revised Min-Sum decoding algorithm is proposed. The fixed-point simulation result and hardware implementation show that this algorithm can improve decoding throughput and reduce iteration.
