matlab仿真进行信道编码，有编译码的改善后的误码特性，信号--外编码--内编码--信道-内解码--外解码-Matlab simulation for channel coding and encryption to improve the error characteristics, signal -- encoding -- within coding -- channel-decoder -- outside Decoders

自己用matlab与c接口方法编写的可以用matlab调用的C程序，实现Viterbi译码（软硬都可）。使用前在matlab里输入：mex - 文件名.c；-A c file can be used in matlab scr ipt to achive Viterbi Decoding (Error Control Coding) for both Hard Decision and Soft Decision.

进行pcm编码的仿真及学习，通过MATLAB仿真PCM编码流程，并考虑在高斯噪声影响下pcm编码的误码情况并绘图-Pcm encoding performed simulation and learning through MATLAB simulation PCM coding process, and consider Gaussian noise pcm coding error situation and drawing
