matlab高阶谱工具箱 有维格纳2阶，3阶切片(Wigner order spectrum matlab toolbox has two bands, three bands sliced)

这是一篇matlab模糊聚类方法分析的一篇例文，参考价值很大(This is a matlab fuzzy clustering analysis of a Liwen, a great reference value)

MATLAB FDATOOL的使用和具体的使用方法(MATLAB FDATOOl)

文件包含两个m文件，一个是QPSK的主函数文件和单径的瑞利衰落信道fade.m文件，实现的对qpsk的过程进行了仿真（在瑞利和高斯信道的作用下）。绘制出了在各个阶段的波形图(M file contains two files, one file is the main function of QPSK and single path Rayleigh fading channel fade.m file qpsk the process of implementation of a simulation (in the Rayleigh and Gaussian channel under the action.) Drawn out at each stage of the waveform)

说明：  用Matlab实现的隐蔽马尔可夫模型（Hidden Markov Model:HMM)(Hidden Markov Model(HMM) with matlab)

实现短时傅里叶变换的功能。分为两种方式：1、matlab自带函数；2、自行编写程序。自行编写的程序效果更加，绘制时频分布图更清晰准确。（附带几篇参考文章）(Short time Fourier transform. Divided into two ways: 1 matlab own function own programming. Write your own program was more plotted frequency distribution more clearly and accurately. (With several reference articles))

4步标定法，主要是实现计算机数字图像处理摄像机的标定，操作简单，比较实用(4-step calibration method is to achieve a computer digital image processing camera calibration, easy operation, more practical)

rake接收机仿真，参考程序walsh码扩频，三径瑞利信道，三种合并方式(rake receiver simulation, the reference program walsh code spreading, three-path Rayleigh channel, three kinds of merger)

这次是对添加水印的图像中添加一种高斯噪声的matlab程序(The watermark image is added to add a Gaussian noise process)

编写的qpsk源程序，实现qpsk的的调制解调(Qpsk written source, to achieve qpsk of the modulation and demodulation)
