中文说明：包含217卷积码的编码与译码仿真程序，编码和译码M文件是自己编写的不是用的matlab通信工具箱，通过运行调试可以帮助弄懂卷积编码和维特比译码算法的思想。main.m是主文件运行该文件即可得到仿真实验结果
English Description：
Including 217 convolutional code encoding and decoding simulation program, encoding and decoding m file is written by ourselves, not by using MATLAB communication toolbox, through running debugging can help understand convolutional coding and Viterbi decoding algorithm. Main. M is the main file. Run this file to get the simulation results
