非规则LDPC码在AWGN信道下的性能仿真，码长1024，码率0.5，调制方式QPSK(simulation of LDPC codes in AWGN channel)

本程序用差分进化算法来优化神经网络，克服局部最优，使得全局最优，亲测可用(This program uses differential evolution algorithm to optimize neural network, overcome local optimum, make global optimum and pro-test available.)

matlab曲面拟合强烈向做实验数据处理的朋友推荐，该函数特别适合空间点的曲面拟合，matlab中对于此类数据点似乎只能用griddata差值计算，并且效果不怎么好；至于B样条拟合，其外扩数据点的选取不是一般的matlab用户所能掌握的，同时对于非网格数据的转换也是一个问题。。。(matlab surface fitting is strongly recommended to friends experiment data processing, the function surface fitting particularly suitable space point the matlab for such data points seems calculated only use griddata difference, and the effect is not very good As for the B-spline Article fitting the outer expanding selection of data points is not an ordinary the matlab user can master, while for non-grid data conversion is also a problem. . .)

说明：  谢菲尔德大学的MATLAB遗传算法工具箱，已经试过，很好用，在这里分享给大家。完全解压后将文件放到matlab的toolboxs里，再打开matlab的set path添加保存(The MATLAB Genetic Algorithm Toolbox at the University of Sheffield has been tried and used very well and is shared here. After fully decompressing, put the file into the toolbox of matlab, and then open the set path of matlab to save it.)

This file is about DSP data manual, very useful for learning DSP people hope that through this test
