Adaptive Filter. This script shows the BER performance of several types of equalizers in a static channel with a null in the passband. The script constructs and implements a linear equalizer object and a decision feedback equalizer (DFE) object. It also initializes and invokes a maximum likelihood sequence estimation (MLSE) equalizer. The MLSE equalizer is first invoked with perfect channel knowledge, then with a straightforward but imperfect channel estimation technique. (Adaptive Filter.

两个16个阵元的平面阵波束形成。很好用的(16 element array of two plane array beamforming. Very good use)

粒子群算法,自己编的一个程序，可以实现，运行main函数(Particle Swarm Optimization)

y=d2wavelet(x,Fs,level) does the 2nd order Daubechies Wavelet Transform of signal x with a sampling frequency Fs and the DWT is decomposition is done upto a level It returns the matrix of all decompositions and the final approximations. Instead of using the matlab s inbuilt DWT function, this file explains the algorithm for DWT. Mostly useful for learning & academic purposes. For other wavelets, the filter values alone can be changed or WFILTERS can be used. The function basically is for Condition Monitoring of rotating equipments by vibration based bearing fault diagnosis by the author. Example: clear all t=[0:0.0003:8*pi] x=sin(5000*t)+sin(1000*t) x=x(1:2^16) level=5 Fs=1/0.003 d2wavelet(x,Fs,level) Thanks for Downloading. Don t forget to rate or comment.

本书主要可以分为两部分，第一本书是基础，主要介绍了matlab的基本图像处理方法；第二部分是应用，主要介绍理论和方法的实际使用。(The book can be divided into two main parts, the first book is the basis, mainly introduces the basic matlab image processing method the second part of the application, the main theoretical and methodological introduction of actual use.)

说明：  一种基于信号二阶统计量的盲源分离方法，SOBI方法，二阶盲辨识方法(SOBI)

说明：  高斯、泊松、瑞丽分布是信道中噪声最基本的几种分布到情况，了解信道噪声情况对于信道去噪是很有必要的(it is very important in the processing of denoising)
