脉冲编码调制程序，采用A律和u律，可在GUI中显示变换前后波形区别并播放声音。(A Pulse Code Modulation program based on A-law and u-law. Can display in the GUI waveform before-and-after difference and play the sound.)

这个是多相滤波的MATLAB程序，做接收机的同学可以参考的(this is a polyphase programme)

说明：  此代码是用matlab软件仿真PAM4信号的传输，自动生成传输数据，在接收端做基本的信号处理，计算出误码率。(This code uses MATLAB software to simulate the transmission of pam4 signal, automatically generate the transmission data, do basic signal processing at the receiving end, and calculate the bit error rate.)

1.分别在两个图中画出δ(n)和δ(n-2)，其中-10≤n≤10，画出U（n）其中-10≤n≤10。 2.分别在两个图中画出x1(n)=cos(2π×20×0.01×n)，0≤n≤10和x2(n)=(0.8)n，1≤n≤6。 3.由上一题，计算y(n)=x1(n)+x2(n)，并画图。(1. Draw the figure at two δ (n) and δ (n-2), where-10 ≤ n ≤ 10, draw the U (n) where-10 ≤ n ≤ 10. 2. Respectively in the two Draw the figure x1 (n) = cos (2π × 20 × 0.01 × n), 0 ≤ n ≤ 10 and x2 (n) = (0.8) n, 1 ≤ n ≤ 6. 3. from the previous question, calculate y (n) = x1 (n)+ x2 (n), and drawing.)

Implementation of 8 point algo and homography

这是关于“噪声调频信号”的仿真模型，已经编译好，直接运行即可(This is on the )

PCap网络组件接口Dephi源码 (PCap network components Delphi source interface)

对KMEANS算法进行matlab实现，有数据支持(On KMEANS algorithm matlab realize, there are data to support)

matlab数字水印 通过这个程序可以给原图象加上水印 但不可以提取！(a watermark sourcecode implemented by MATLAB. By using this program, primary image can be embedded while the watermark cannot be extracted.)

《数字信号处理教程——MATLAB释义与实现》的程序集，其中包括三部分。在examples子目录下本书全部例题的完整MATLAB程序；在subrtdsp子目录下是本书中自编的一些子程序，在运行例题程序时需要调用；这两个程序包是在学完本书后，读者能够读懂理解的。(dsk04 is a " digital signal processing tutorial- MATLAB Interpretation and Implementation" of the assembly, which consists of three parts. In all the examples subdirectory book example of a complete MATLAB programs in subrtdsp subdirectory is some self-compiled subroutines in the book, when running the example program need to call these two packages is in the completion of the book, the reader able to read to understand.)
