Description: This script simulates the classical turbo encoding-decoding system.
It simulates parallel concatenated convolutional codes.
Two component rate 1/2 RSC (Recursive Systematic Convolutional) component encoders are assumed.
First encoder is terminated with tails bits. (Info + tail) bits are scrambled and passed to
the second encoder, while second encoder is left open without tail bits of itself.
Random information bits are modulated into +1/-1, and transmitted through a AWGN channel.
Interleavers are randomly generated for each frame.
Log-MAP algorithm without quantization or approximation is used.
By making use of ln(e^x+e^y) = max(x,y) + ln(1+e^(-abs(x-y))),
the Log-MAP can be simplified with a look-up table for the correction function.
If use approximation ln(e^x+e^y) = max(x,y), it becomes MAX-Log-MAP.- This script simulates the classical turbo encoding-decoding system.

Description: 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.
