信号发生器 可以产生三角波郑玄波！等等 是基于GUI设计的 打家可以参考一下(how are you!)

CRC码生成器和卷积码的仿真程序。其中CRC码可以自定义生成多相式或字符串；卷积码可以自定义约束长度和码长。(CRC code generator and the simulation program convolutional codes. Which the CRC code can customize the generation of multi-phase or string convolutional codes can customize the constraint length and code length.)

解释飞蜂窝用户和宏蜂窝用户之间的通信，以及他们的覆盖问题。(Explain the communication between femtocell user and macro cellular subscribers, and their coverage problem.)

用蒙特卡洛模拟来迭代1000次以后，计算10天后的VaR,特色就是对里面的方差和均值进行差分。里面有详细步骤和方法。(Using monte carlo simulation to iteration after 1000 times, calculate the VaR after 10 days,the characteristic of model is that calculating the the variance and mean 不by difference.There are detailed steps and methods)

总结了五中时频分析方法（STFT,Gabor,WVD,PWVD,SPWVD）,并对个别方法进行了对比。每条程序都有详细的说明(Fifth summarized time-frequency analysis method (STFT, Gabor, WVD, PWVD, SPWVD), and the individual methods were compared. Each program has a detailed description)

利用matlab针对图像进行马氏距离计算(use matlab soft to compute the mahalanobis distance of the image )

说明：  对已知房价数据做二次拟合，从而得出曲线方程，对做未来房价的粗略预测(Known to do on the secondary price data fitting curve equation to obtain, so the future price of crude forecast)
