这个是用来计算Haar-like特征数目的，用MATLAB求的某一个矩形特征的数目(This is used to calculate the number of Haar-like features, with the MATLAB find a certain number of characteristics of a rectangular)

卷积情况下的盲分离,对于初学者非常有用。(Convolution case of separation, is very useful for beginners.)

说明：  语音信号处理工具箱，说明：解压后，然后按照readme文件安装即可。(Speech Signal Processing Toolbox, Note : unpacked, and then follow the readme file can be installed.)

直接序列扩频代码，完成直接序列扩频的扩展功能(Direct sequence spread spectrum code to complete the extended functionality of direct sequence spread spectrum)

rs（255，239）码基于matlab编码，c语言译码，仿真性能优异(rs encoding with matlab,and decoding with c)

再matlab上实现基于扩频的数字水印。图像处理(This is a simple spread-spectrum based informed watermarking implementation in MATLAB. )

设计一维纳滤波器 (1)产生三组观测数据：首先根据s(n)=a s(n-1)+w(n)产生信号s(n)，将其加噪（信噪比分别为20dB,10 dB，6 dB），得到观测数据x1(n), x2(n), x31(n). (2)估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L,N对实验结果的影响。 (A Wiener filter design (1) to produce three sets of observations: first generating a signal s (n) according to s (n) = as (n-1)+w (n), to add noise (20dB SNR, respectively , 10 dB, 6 dB), to obtain observational data x1 (n), x2 (n), x31 (n). (2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss the impact changing L, N of the experimental results.)
