1. 程序中Turbo译码采用了MAP,LOG-MAP，和MAX-LOG-MAP三种算法。 2. 以xxx开头的四个mat文件是四种给定的Turbo码在译码时用到的参数，保存下来的目的是 加快仿真的速度，如果你所仿真的Turbo码不是程序中列出的任意一种，你可以通过函数 trellis来生成自己的相关参数。 3. 程序支持1/2和1/3两种码率的Turbo码，其中1/2码率的Turbo码通过矩阵[1 0 0 1]打 孔得到。在译码时通过对打孔位置添0恢复成1/3码率的码字。 4. 程序中的信噪比表示Eb/N0，通过此参数求得N0，对发送信号进行加噪。(1 program in Turbo decoding using the MAP, the LOG-MAP, and three kinds of the MAX-LOG-MAP algorithm.)
