说明：  编程实现图像DCT高通、低通滤波器并与傅立叶变换做比较(Programming image DCT high pass, low pass filter and compared with the Fourier transform)

这里给出几幅多聚焦图像，为大家做图像融合处理，一共两组图像(Here are the pieces of multi-focus image, for everyone to do image fusion, a total of two sets of images)

使用MySin函数生成一个幅值为3、频率为10Hz的正弦信号x(t)，其中dt分别为0.1s、0.08、0.05s、0.005s。绘出四个正弦信号波形及其单边幅值谱(Use MySin amplitude function generates a 3, a frequency of 10Hz sinusoidal signal x (t), where dt respectively 0.1s, 0.08,0.05s, 0.005s. Sinusoidal waveform and draw four-sided amplitude spectrum)

这是一读取信号进行FM调制，可以是CMA盲均衡算法对FM信号做处理(This is a read signal to FM modulation, and can be CMA blind equalization algorithm processing the FM signal with)

基本混沌系统的同步程序，用matlab编写，并且在其他系统中也是通用的。(chaos system is made by matlab language,which is suitable for other system.)

filter design for communication system

MATLAB课件，有利于学习应用MATLAB (MATLAB software is conducive to studying the application of MATLAB )

Matlab program for ZF equalization

This file is the program to change decimal number to binary number.

说明：  BP神经网络识别手写体数字，BP(back propagation)神经网络是1986年由Rumelhart和McClelland为首的科学家提出的概念，是一种按照误差逆向传播算法训练的多层前馈神经网络，是应用最广泛的神经网络。(Recognition of handwritten digits by BP neural network)
