摘要
提出了一种高速RS+QC-LDPC级联码编码器,介绍了这种级联码在FPGA平台上的实现方法,并对其性能进行了评估.重点介绍了RS+QC-LDPC级联码的各种优化技术,如基于二次扩展的QC-LDPC编码方法,采用交织技术,合理的搭配RS码和QC-LDPC码的码长、码率以达到最好的性能.经过优化,级联码编码器的吞吐量可以达到2.25Gbit/s以上.
In this paper,a novel design of RS＋QC-LDPC cascade encoder is presented,furthermore,the based FPGA implementation of the encoder is introduced.The throughput of cascade encoder surpasses 2.25G bit/s with using several optimization techniques,such as duplex expansion QC-LDPC code,interleave coded and reasonable code length and code rate.
