在无线通信系统中常用的卷积码编码算法，并且加了打孔技术-Commonly used in wireless communication systems convolution coding algorithm, and added drilling technology

这个是数据打孔重传程序的源代码，很值得我们学习哦，希望大家喜欢。-This is a data retransmission procedures perforated the source code, it is worth learning Oh, I hope everyone likes.

根据打孔法，依托对各级变量节点进行分类的方式实现各种变速率LDPC码(According to the hole drilling method, variable rate LDPC codes are implemented by classifying the variable nodes at all levels)
