for cross entropy implementation

the LDPC code program

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。正所谓 一分钱一分货啊，优化效果不总是令人满意。(This procedure is the most basic particle swarm optimization procedures, using Matlab implementation, is very simple. Only a few dozen lines of code. One is the so-called sub-penny ah goods, and optimize the result is not always satisfactory.)

说明：  MATLAB椭圆你和函数，还好吧，但是我没太看懂~(MATLAB elliptic function you and also Well ~)

this m.file produces channel coefficient with some error, in which the estimation error follows a random variable with zero mean and variance of MSE. lat is the latitude of BS places at different cells which is used to determine the number of BSs in the networks
