This a software runing on the Matlab. it is used in the channel coding simulation. It i nclude DVB-S2 LDPC and turbo Covolution. and block turbo code, You can choose which channel coding to run. it ru n the encoder and add white noise in the channel.

Turbo码，LDPC码（低密度奇偶校验码）均具有接近Shannon限的性能， 是目前便译码研究的热点。Turbo码在低信噪比情况下的性能优于其它各种编码 方式。而LDPC码的描述简单，具有较大的灵活性，当码长足够长时具有比Turbo 码更为良好的性能，其译码复杂度低于Turbo码。-Turbo code, LDPC code (LDPC) all have close to Shannon limit performance, it is the firm' s resear
