说明：  小波分析理论与Matlab 7实现 添加了2次提升的小波程序 详细介绍了7的新功能(Theoty of Wavelet And Implement of Matlab 7 appended procedures of two-lever-wavelets ,and introduced the new function of matlab 7 )

AR模型的实现流程及matlab代码 有详解(The implementation process of the AR model and the matlab code have detailed explanations.)

PSK调制的原始matlab代码，可以直接使用，打打基础(matlab code for PSK modulation )

负正弦加白噪声随机过程下使用MUSIC方法进行信号频率估计仿真，信号样本数去1000，估计的自相关矩阵为8阶，分别采用AIC和MDL准则估计信号源个数，并画出相应的MUSIC频率估计谱线。(Negative sine plus white noise random process method using MUSIC frequency estimation simulation, signal samples to 1000, the estimated autocorrelation matrix of order 8, AIC and MDL criteria were used to estimate the number of signal sources, and draw the corresponding MUSIC frequency spectrum estimation.)

Program to plot the BER of OFDM in Frequency selective channel

1拍摄一张包含两本成一定夹角放置的书的图像2获得书的边缘二值图像3通过hough变换在原始灰度图像中用红色标记出书的边缘，计算两本书的夹角(1 shot 1 into a certain angle contains two books placed on the edge of the image 2 receive the binary image 3 by hough transform the original gray image using the red mark the edge of a book to calculate the angle between the two books)

the geometry of a diffraction grating, a common illustration in textbooks of optics, spectroscopy, and analytical chemistry. Sliders on the figures allow real-time interactive control of the incidence angle, grating ruling density (lines/mm), wavelength, and diffraction order.(the geometry of a diffraction grating, a commonillustration in textbooks of optics, spectroscopy, and analytical chemistry.Sliders on the figures allow real-time interactive control of the incidence angle, grating ruling density (lines/mm), wavelength, and diffraction order.)
