本程序设计了一个数字低通滤波器，以滤除加入的高斯白噪声，很好的实现功能。(The program design of a digital low-pass filter to filter out the add white Gaussian noise, achieve good function.)

复旦大学自动控制理论ppt第1章,关于matlab的概述(Fudan University, Automatic Control Theory Chapter 1 ppt, an overview on matlab)

伪随机二位信号，用于系统辨识的特殊输入信号，可实现特定的功能，望多多学习。(Two pseudo-random signals for system identification of special input signal, to achieve specific functionality, hope to learn a lot.)

本代码主要用于处理后的图像质量评价，其评价指标综合为一个程序中，其中评价指标有SSIM,PSNR,ERGAS。程序使用matlab编程，根据自己的应用习惯做微调即可(This code mainly for image quality uation after treatment, the uation of a comprehensive program, including uation indicators SSIM, PSNR, ERGAS. Program using matlab programming, according to their own habits application can do fine tuning)

粒子群优化算法(PSO)是一种进化计算技术(evolutionary computation)，有Eberhar博士和kennedy博士发明。源于对鸟群捕食的行为研究 ，PSO同遗传算法类似，是一种基于叠代的优化工具。 (Particle Swarm Optimization (PSO) is an evolutionary computation technique (evolutionary computation), and has Eberhar Dr. Dr. kennedy invention. Stems from the behavior of predatory birds, PSO with genetic algorithm is similar to an iterative optimization-based tools.)

说明：  用C来编写MEX文件调用MATLAB，很有实用性(MEX using C to write a document called MATLAB, very practical)

说明：  ADUC7026原理图,很好用,给大家做个参考(ADUC7026)

MIMO-OFDM,是汪裕民那本书的。大家餐卡一下！(MIMO-OFDM, is Wang Yumin that book. Meal card you look!)

如何计算矩阵数据的协方差矩阵。还有在什么情况下只能计算均值、方差，而不能计算协方差，什么情下，只能计算协方差，但不能计算协方差矩阵。(How to calculate the matrix data covariance matrix. And under what circumstances can only calculation mean, variance, and not calculation covariance, what feeling, can only calculation covariance, but not calculation covariance matrix.)
