摘要

利用密度演化(DE)和中断边界分析，研究了分组衰落信道(BFC)上根低密度奇偶校验码的二进制消息传递(BMP)解码器。在此基础上提出了适用于根ldpc码的先验信道估计技术。实验结果表明，在信道软判决可用的情况下，BMP解码器可以获得完全的分集性能。

Full diversity binary message-passing decoders for block fading channels

Binary message-passing (BMP) decoders for root-low-density parity-check (LDPC) codes over block fading channels (BFC) are studied using density evolution (DE) and outage boundary analysis. A-priori channel estimation techniques suitable for root-LDPC code are proposed based on DE. The results show that BMP decoders can achieve full diversity performance if soft decisions from the channel are available.
