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

5G通信必须用到的编码：Turbo码是Claude.Berrou等人在1993年首次提出的一种级联码。基本原理是编码器通过交织器把两个分量编码器进行并行级联，两个分量编码器分别输出相应的校验位比特；译码器在两个分量译码器之间进行迭代译码，分量译码器之间传递去掉正反馈的外信息，这样整个译码过程类似涡轮（Turbo）工作。因此，这个编码方法又被形象地称为Turbo码。Turbo码具有卓越的纠错性能，性能接近香农限，而且编译码的复杂度不高。-5G communication must be used

In the early nineties, turbo codes and its new iterative decoding technique were introduced, employing this new coding scheme and its decoding algorithm, it was possible to achieve performance within a few tenths of a dB the Shannon limit for a

Turbo codes were first proposed by Berrou (and others) in 1993. Since its introduction, turbo code has become the coding technique of choice in many communication and storage systems due to its near Shannon limit error correction capability. Thes
