小波包在信号消噪中的应用，利用小波包对给定含早信号进行消噪处理(Wavelet Packet Denoising in the application of wavelet packet to a given signal denoising with early treatment)

说明：  利用中心极限定理产生标准正态分布随机数，并进行检验；编制一个界面，产生（0，1）均匀分布随机数，并检验其主要统计量性质。(Central limit theorem using the standard normal distribution random number generation, and tested the preparation of an interface, resulting in (0,1) uniformly distributed random numbers, and verify the nature of the main statistics.)

图像合成 内容：随意选择两个图像，选择其中一张图像中的部分内容，利用 matlab 编程添加到另一张图像中；所有的代码添加了注释(the choice of two images, choose one of parts of the image, by using matlab Programming is added to another in the image All of the code to add comments )

LDPC分层译码的matlab程序，LDPC在WIMAX。WIFI应用广泛(layered decoding of LDPC , matlab codes)

dbpsk信号的调制解调matlab代码实现的一个例子，调制时差分编码，这样用1bit延迟差分检测的结果，直接就是原码，解调采用1bit差分延迟检测．(DBPSK signal modulation and demodulation matlab code an example of differential modulation encoding, such 1bit delay with the results of differential detection, direct that the original code, demodulation using 1bit delay differential detection.)

Delaunay triangulation is one of the most well known algorithms for space tesselation. Dynamic Delaunay triangulation, in which you can update the input points using a predefined matrice for saving points, is presented in this document.

It can be easily seen the above analysis that the shootthrough duty ratio is always constant. This can be reconfirmed a different perspective below

运行程序得到微分方程中x1随参数omega变化的分岔图。omega的范围选取可以调节。(Run the program to be differential equations with parameters x1 bifurcation diagram omega changes. omega scope of selection can be adjusted.)

一个多用户检测器的matlab代码程序 采用m序列作为扩频码 非常不错(very good)
