? 了解3G移动通信网中关键技术CDMA的实现原理 ? 掌握matlab编程，实现CDMA原理仿真 ? 掌握matlab语言对于码分复用技术仿真的功能(Understanding the Implementation Principle of the Key Technologies of CDMA in 3G Mobile Communication Network Master the MATLAB programming and realize the simulation of the principle of CDMA Master the function of MATLAB language in simulation of code division multiplexing technology)

LDPC校验矩阵生成、高斯消去法编码、BP译码程序，可以作为自己编写LDPC编译码程序的参考。因为matlab代码效率不高，所以这个程序仿真起来比较慢.(LDPC check matrix generation, Gaussian elimination coding, BP decoding procedure can be used as its own procedures for the preparation of LDPC codec reference. Because matlab code efficiency is not high, so this process is relatively slow simulation together.)
