induction machine closed loor v/f control simulink model

This is excersis solution of the chapter 7th of AFT text book which i have uploaded previopusly.

本程序完成地震信号的提取检测。以往都是利用地震信号的能量比，此处创新选择地震信号的过零点作为边缘提取的判断。新方法效果不错。(The process is complete extraction of seismic signal detection. Past, the energy ratio of seismic signal, where innovation and choice as the seismic signal zero-crossing edge detection judgments. The new approach is very effective.)

说明：  灰色预测模型matlab实现此模型可以做一些长期的预测(Gray prediction model matlab can do this model to achieve some long-term forecast)

随机线性分组编码，信道编码，纠错编码，检错编码(Random linear block coding, channel coding)

DM编码的实现，可以比较好的帮助初学者DM编码的实现，可以比较好的帮助初学者

关于小波去噪的MATLAB源程序序实现图像和信号的去噪可直接使用。 (On Wavelet Denoising MATLAB source sequence image and signal denoising can be used directly.)

稀疏快速傅里叶变换，是一种利用信号频域稀疏特性，只需通过信号部分采样点就可高概率恢复信号频谱的快速傅里叶变换算法。(Sparse Fast Fourier Transformation ，SFFT)

这个程序能清楚显示灰度图形的灰度直方图，并能进行平滑与滤波处理，方便程序员观察了解图像。(this procedure will clearly show that the gray-scale graphics histogram, and for smoothing and filtering. Observer allows programmers to understand images.)
