中卷积码就是一种较好的信道编码方式。这种编码方式同样是把k个信息比特编成n个比特，但k和n通常很小，特别适宜于以串行形式传输信息，减小了编码延时。这里是卷积码的viterbi算法C源代码。

-Of convolutional codes is a better way of channel coding. Such are the same encoding k information bits into n bits, but k and n is usually very small, especially in serial form suitable for transmission of information, reduces the latency encoding. Here are the viterbi algorithm for convolutional code C source code.
