摘要 本文基于低密度奇偶校验码(Low-Density Parity-Check,LDPC)译码中的Turbo迭代的消息传递(Turbo Decoding Message Passing,TDMP)算法,设计了一种符合DMB-T标准的LDPC译码器。文章中结合DMB-T标准中H矩阵的特点,提出了一种基于双堆栈的快速Bahl-Cocke-Jelinek-Raviv(BCJR)译码运算的软输入软输出(SISO)译码器模块设计,并提出了一种基于循环偏移的可编程交织器设计。 In this paper, we designed a TDMP-LDPC decoder for DMB-T Standard. Considering the architecture of the parity check matrix in DMB-T, we designed a fast BCJR decoding SISO module based on duel stack structure. We also designed a programmable bi-directional network based on shifting method.
