说明：  使用维纳滤波器对信号进行处理，得到噪声状况下的信号，这个滤波器是数字信号处理中非常经典的一个。代码里还提供了维纳的AR参数估计(Wiener filter to use signal processing, noise signal conditions, this filter is digital signal processing in a very classic. There is also a code of the AR Wiener Parameter Estimation)

可自行设置参数产生SCM信道，支持MIMO等功能(can set your own parameter to create SCM channel,support MIMO an other function.)

matpower代码包，用于电力系统潮流计算、优化等等(matpower4.1 source code)

此程序实现构造小波基 (this program structure of this small Porgy program structure wavelet)

数字信号处理实践方法，从一到三囊括了数字信号处理的模数变换、DFT变换、Z变换、滤波器设计等(Digital signal processing practices, from 1-3 to include digital signal processing of analog-to-digital transformation, DFT transform, Z transform, filter design, etc.)

说明：  车牌倾斜校正程序，将车牌边界与图像边界不平行的图像进行旋转，使其平行，可用于车牌识别。(Plate tilt correction procedure, the plate boundary is not parallel with the image border to rotate the image, a parallel can be used for license plate recognition.)

关于三相SVPWM仿真的模型，我做电力电子仿真作业的一道题，花了很多时间下载和阅读文献，最后总算成功了，只是仿的结果有点慢，一直找不到为什么。 注意：此模型仿真时需要svpwm.m这个文件，并且matlab软件版本为Matlab7.1。(About three-phase SVPWM simulation model, I do the job of power electronic simulation of a question, spend a lot of time to download and read the literature, but finally succeeded, but the result of imitation of a little slow, could not find why. Note: This model simulation requires svpwm.m this file and matlab software version Matlab7.1.)
