小波阈值去噪的程序，实现对图像的去噪，也可以用于对简单的语音和其它信号(Wavelet threshold denoising procedures)

进行多尺度小波变换，能够得到较一般的小波变换更好的分解结果(Multi-scale wavelet transform)

这是一个基于贪婪算法和右手法则基础上得到的路由仿真程序。对于初学者还是有借鉴意义的！(Greedy Perimeter Stateless Routing for Wireless Networks and right hand rule )

本文主要叙述的是利用MATLAB软件实现图像的几何操作。利用imresize() imrotate() imcrop() 等函数实现图像的缩放，选转，剪切。 在对图像的几种几何操作中，图像的缩放和旋转都要用到插值操作。(This paper describes the use of MATLAB software images of geometric operations. Use imresize () imrotate () imcrop () Function Image Scaling , elected to the shear. In the image of several geometric operation, image scaling and rotation should be used interpolation operation.)

说明：  雷达信号去斜处理方法：去斜处理(宽带的匹配滤波)Stretch方法是针对线性调频信号而提出的, 其方法是将输入信号与参考信号 (经适当延迟的本振信号, 延迟量通常由窄带信号测距结果估计出) 混频(Radar signal de-obliquation processing method: The Stretch method of deskew processing (wideband matched filter) is proposed for linear frequency modulation signal. Its method is to mix the input signal with the reference signal (local oscillator signal with appropriate delay, the delay is usually estimated by narrowband signal ranging result))

在功率谱估计中采用Bartlett法对信号进行功率谱估计。(In the power spectrum estimation method used in Bartlett signal power spectrum estimation.)

说明：  实现单目双焦测距算法 实现单目双焦测距算法(English Vers)

FIR数字滤波器设计，采用了matlab的图形界面设计。(FIR digital filter design, use of matlab graphical interface design.)
