3条固定路径的AWGN多径信道中的QPSK系统进行BER性能仿真，并与理想信道(没有多径)作比较。 需要的支撑子程序为qpsk_berest.m,vxcorr.m,random_binary.m.(Three fixed-path multipath AWGN channel QPSK system BER performance simulation, and with the ideal channel (no multipath) for comparison. Need the support of subprogram for qpsk_berest.m, vxcorr.m, random_binary.m.)

用于在MATLAB中绘制多坐标轴，将多个变量绘制在一张图中(MATLAB is used to draw multiple axes, multiple variables are plotted in a graph)

进行可靠度分析有效方法 画出数据概率分别vu 如 (for reliable method N = FREQDM(Y) bins the elements of Y into 10 equally spaced containers and returns the frequency of each container. If Y is a matrix, FREQDM works down the columns. N = FREQDM(Y,M), where M is a scalar, uses M bins. )

Exponential distribution function by uniform distribution function

用matlab实现去趋势互相关分析的DCCA算法，将两组数据分析其协方差，最后得到DCCA指数，并进行T检验(DCCA algorithm using matlab detrended cross-correlation analysis, two sets of data to analyze the covariance last DCCA index, and T-test)

matlab的支撑向量机工具箱的使用介绍，比较实用的文档(matlab toolbox for the use of support vector machine introduced more practical document )

说明：  用其中一半的数据采用ANN-BP算法设计分类器，另一半数据用于测试分类器性能。(Half of the data used by ANN-BP algorithm design classifier, the other half of the data used to test the classifier performance.)
