著名的欧洲数字卫星广播标准，详细给出了帧结构、LDPC码和BCH码。-Digital Video Broadcasting (DVB) Second generation framing structure, channel coding and modulation systems for Broadcasting, Interactive Services, News Gathering and other broadband satellite applications

The Low-Density Parity-Check codes are among the most powerful forward error correcting codes, since they enable to get as close as a fraction of a dB the Shannon limit. This astonishing performance combined with their relatively simple decoding

结构化 LDPC 码也被称为准循环（Quasi-Cyclic）LDPC 码。QC-LDPC 码已经广泛应用 IEEE 802.11、IEEE 802.16、DVB-S2 等系列标准
