matlab下用小波去除随机噪声的一个例子，希望对大家有用(matlab remove the random noise using wavelet under an example, we hope to be useful)

说明：  用MATLAB模拟静态散斑，成像和非成像散斑，方便初学者学习(Simulation with MATLAB static speckle, speckle imaging and non-imaging, easy for beginners to learn)

说明：  系统模拟仿真了OFDM在有线信道的时域均衡算法。(failed to translate)

很实用的matlab SVM OSU_SVM3.00工具箱，适合在7.0以上的版本安装使用(very good)

精通matlab最优化计算随书带的源码，包括线性规划，整数规划，pso，GA等(Proficient in matlab optimization calculation with the source code with the book, including linear programming, integer programming, pso, GA etc.)

非平稳信号的处理方法，时频分布及、常用方法简单例子(Non-stationary signal processing methods, examples of commonly used methods)

此为雷达对抗的基本知识.对初始学习的人有一定的帮助.(This is the basic knowledge of radar confrontation. For the initial study were certainly helpful to them.)

说明：  设计一个有干扰的直接序列扩频通信系统， PN码由m序列产生器产生，经过高斯白噪声信道。在接收端接收到的信号包括“有用信号+高斯白噪声+干扰”，将接收信号进行解扩，判决，得到用户的信号检测结果，绘制不同的扩频增益（增益值为10，30，50）下，误比特率随信噪比Eb/N0的变化曲线。(Design of a direct sequence spread spectrum interference system, PN code generated by the m sequence generator, after white Gaussian noise channel. Receives the signal at the receiver, including &quot useful signal+ Gaussian white noise+ interference&quot , will receive the signal despreading, judgments, get the user' s signal test results, draw a different spreading gain (gain value of 10,30, 50), the BER curves with the signal to noise ratio Eb/N0.)
