实现了（4，1，6）型卷积码的维特比译码算法，采用了极大似然算法。介绍了软判决维特比译码算法过程的三个步骤：初始化，度量更新和回溯译码。

对码率为1/n的递归卷积码（系统码！）的最大似然译码，采用相关度量，截断长度为1024，最大状态数为1024 -On the bit rate for the 1/n recursive convolutional codes (system code!) Of the maximum-likelihood decoding, using the relevant measure to cut off a length of 1024, the largest number of state

卷积码的编译码代码，译码为维特比译码算法。-Convolutional codes and decoding the code for the Viterbi decoding algorithm.

用C++实现卷积码的编码和译码，整个过程融为一体，可以实现从卷积码的编码到译码最后还原本来面目的全套实现-Full realization of the convolutional code encoding and decoding with C++ achieve integration of the entire process, and finally restore the true colors can be achieved from the convolutional code
