CMMB中采用的是一种非常特殊的LDPC码，这是CMMB标准中LDPC码的相关专利文档，看过后就会明白其编解码原理，从事CMMB开始人员必看此文档

一篇关于CMMB中LDPC编码译码的论文，解释得很详细，还有硬件(FPGA)实现方法-CMMB in an article on decoding LDPC coded paper to explain it in detail, as well as the hardware (FPGA) Implementation Method

讲述CMMB中LDPC的结构和其编译码算法-CMMB in LDPC about the structure and its encoding and decoding algorithms
