摘要
对空间数据系统委员会(CCSDS)推荐的QC-LDPC码进行了研究,给出了改进的分层译码算法。基于改进的分层译码算法设计部分并行结构QC-LDPC译码器,译码速率较快,适合应用需求,并通过仿真验证所设计的译码器的性能。
The Quasi-Cyclic LDPC(QC-LDPC) codes chical decoding algorithm is proposed. The design of the proved hierarchical decoding algorithm decodes fast and is the design are verified. which were proposed by CCSDS is investigated, and an improved hierar- QC-LDPC decoder which has partial parallel architecture based on im- suitable for practical applications, and by simulation the performances of
