一个改进型的正弦波叠加发实现平坦衰落的程序，由于采用了带有随机相位的方法，使得生成的信道具有独立性，适合MIMO系统的信道仿真()

说明：  iPhone真机调试及如何上传到Apple Application Store平台。(iPhone-device debugging and how to upload to the Apple Application Store platform.)

绘图并还有指定的legends and colorbars(his function will create a new figure containing the axes/uipanels specified, and also their associated legends and colorbars. )

灰色预测模型,可以做变形监测预测分析，交通控制和预测分析，金融分析(Gray prediction model, deformation monitoring can do predictive analysis, traffic control, and predictive analysis, financial analysis)

Welch功率谱密度是用改进的平均周期图法来求取随机信号的功率谱密度估计值。Welch法采用信号重叠分段、加窗函数和FFT算法等计算一个信号序列的自功率谱估计(PSD如上例中的下半部分的求法)和两个信号序列的互功率谱估计（CSD）。MATLAB信号处理工具箱函数提供了专门的函数PSD和CSD自动实现Welch法估计，而不需要自己编程。(method of power spectral density plot )

多个微电网的并网模型，采用的是SPWM控制的方法(And a plurality of micro grid network model, using the method SPWM control)

Matlab软件在通信仿真中的应用，适合初学者参考。文件为pdg格式，需下载超星浏览器才可阅读。(Matlab simulation software application in communication, suitable for beginners. File format for PDG, need to download the chaoxing browser.)

说明：  使用matlab实现结构光在大气湍流中传输，并且实现了通信实验以及误码率的检索。(Matlab is used to realize the transmission of structured light in the atmospheric turbulence, and the communication experiment and error rate retrieval are realized.)

隐马尔科夫模型标准源代码，适用于matlab,使用时添加addpath到解压目录即可(HMM code)
