实现matlab直方图的网格填充，斜线角度可以通过调整其中的变量A的值(The realization of grid matlab histogram filling, slash the perspective of the variables by adjusting the value of A)

从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力，进行实验仿真，比较不同的窗函数，不同的数据长度对Welch法谱估计质量的影响，并分析了造成这些影响的原因。(The paper mainly introduces the principles of Periodogram method of classical PSD estimation,analyzes the deficiency of Periodogram method in theory,and makes use of Welch to amend Perodogram method. By the use of simulation in Matlab, the impacts of different window function and different lenghth of data on estimation quality of Welch are discussed and the reasons of the impacts are analyzed.)

遗传算法函数介绍及实用代码，保证能运行，并加上了程序解释和运行结果(Genetic algorithms and practical code function introduced to ensure that will be able to run, with the procedures explained and the results)

人脸识别的matlab程序，不过是一个主程序界面，要是用的话还得调用很多的子程序(Face recognition matlab program, but is a main program interface, if used, then have to call a lot of subroutines)

由于多径和移动台运动等影响因素，使得移动信道对传输信号在时间、频率和角度上造成了色散，如时间色散、频率色散、角度色散等等，因此多径信道的特性对通信质量有着至关重要的影响，而多径信道的包络统计特性成为我们研究的焦点。根据不同无线环境，接收信号包络一般服从几种典型分布，如瑞利分布、莱斯分布和Nakagami-m分布。(Because multipath and mobile and other sports influence factor, makes mobile channel in transmission in time and frequency signal and Angle caused the dispersion, such as time dispersion, frequency dispersion, Angle dispersion, and so on, thus multipath channel of communication with the characteristics of quality is very important, while the effect of multipath channel (the statistical properties become the focus of our research. According to different wireless environment, receiving signals envelope general subject to several typical distribution, such as Rayleigh distribution, rice distribution and Nakagami-m distribution. )
