对信号进行小波包分解，得出能量分布图，然后根据分解结果处理信号！(Wavelet packet decomposition of signals obtained energy distribution and signal processing based on decomposition!)

数字信号matlab程序,是科学出版社编的书的上机作业(IT is matlab homework,it is ok,)

说明：  专家pid控制仿真程序，可以共同学习！希望大家多多支持！(Expert pid control simulation program)

文章：Automatic Image De-Weathering Using Curvelet-Based Vanishing Point Detection 的对应代码(matlab code for Automatic Image De-Weathering Using Curvelet-Based Vanishing Point Detection )

使用时域有限差分法编写的计算散射截面的简单程序(Scattering cross section is calculated using a simple program written in finite difference time domain method)

用C语言编写的模糊PID，可以用在MATLAB的仿真环境，也可以用在其他地方。(C language with the fuzzy PID, can be used in MATLAB simulation environment can also be used in other places.)

在符号间干扰情况下，通过自适应均衡消除码间串扰的影响。均衡算法采用LMS，简单的线性横向滤波器(In case of ISI channel,we exploit adaptive equalization with LMS alogithm to defend the influence. )

这是关于UKF（无味卡尔曼滤波算法）算法的matlab程序(This is on the UKF algorithm matlab program)

这是数字信号处理的一本专业书，里面有许多的经典的例子，可以作为大家学习数字信号处理的教材。(This is a digital signal processing of a professional book, there are many classic examples, as we learn from digital signal processing of materials.)

在MATLAB环境中，进行数字图像处理中常用到的小波函数系列之二(In the MATLAB environment, to carry out commonly used in digital image processing of the wavelet function of the Second Series)
