一个压缩感知的信号处理应用

说明：  介绍了一种用于ip电话的自适应回声消除器，采用LMS自适应滤波器实现。首先通过MATLAB进行LMS算法的步长选择,并用生成的符合G.168要求的带限CCS测试信号对回声消除器的性能进行了测试(Introduced a kind of adaptive echo cancellation ip phone device, using LMS adaptive filter. Carried out by MATLAB first step LMS algorithm selection, and use the resulting band-limited meet G.168 requirements of CCS test signal on the performance of echo cancellation devices were tested)

Write a MATLAB function lls_rd.m (rd stands for rank de… cient) to solve the LLS problem

比较反滤波和维纳滤波对一幅图像复原的效果。从两方面出发，一是对运动模糊和均值模糊复原的能力，二是抗噪能力，各种情况分别都进行了对比(Comparison of inverse filtering and Wiener filtering on an image restoration results. Proceed in two ways, first on the motion blur and the mean fuzzy recovery capability and noise immunity, all cases are compared separately)

通过腐蚀，去轮廓等操作去除图像背景，适合matlab初学者认识程序。(Corrosion, go to outline operation to remove the image background for Matlab beginners understanding of the program.)
