Turbo_code_simulation
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.)

说明： ：文章分析了轻型高压直流输电的基本原理，通过采用定直流电压、定交流电压的控制方式，建立了基于MATLAB的轻型直流输电系统的仿真模型，并以一个单机系统为例，分析了系统的控制模型。通过对三相
接地短路的分析，验证了所建立的仿真模型和控制系统的正确性和合理性，为进一步研究轻型直流输电系统的物理模型奠定了理论基础。(M ATLAB sim ulation of HVDC light system)

CDMA Simulation Using MATLAB
This program models a simple implementation of CDMA technology. It considers multiple bit data streams sent by any number of senders across a common channel. Each sender uses a unique code word, given by the Walsh set, to encode its data, send it across the channel, and then perfectly reconstruct the data at the receiver.
The simulation utilizes these simplifications:
1. The individual data streams share the same bit length.
2. The code words are determined using the Walsh set to create orthogonal code words.
3. The spreading factor M of each code word is identical.
4. All users (data streams and codes) are synchronized in time.
5. Set-up and hold times of real-world systems are ignored.
6. The channel through which the data passes is ideal.
