一个自然梯度的盲源分离matlab算法,希望对大家有用(A natural gradient algorithm for blind source separation matlab hope for all of us)

说明：  利用Matlab可视化编程设计一个界面，实现对几种常见分布的随机抽样并进行曲线拟合，最后用图像直观地表现出来(Using Matlab to design a visual programming interface, to achieve some common distribution of random sampling and curve fitting, and finally with the image shown visually)

this is matlab program for pi/4 qpsk modulation

The Support Ve ct or Machi ne So fa r we have used a reference as sumpt ion tha t there exists a linear classifier that has a larg e ge ometric margin, i.e., whose decision b oundar y is we ll separa ted from all the training images (e xamples). Such a larg e margin classifier seems like one we would like to use. C an’t we find it more directly? Yes, we can. The clas sifier is known as the Support Ve ctor M achine or SVM for short.

该程序用于多普勒频率估计，可以估计多普勒模糊数与基带多普勒频率，从而得到解模糊情况下的多普勒频率，算法基于IEEE文章提出的wavelength diversity 算法所写的。(This programme is used to resolve the absolute doppler frequenc without doppler ambiguity.The algorithm is based on the wavelength diversity idea proposed by the IEEE paper.)

一步线性预测与Weiner滤波的比较，含GUI界面.(Step linear prediction compared with the Weiner filter, with GUI interface.)

这个文件编程实现了正弦调频的频谱图分布和乔伊-威廉斯分布，通过观察我们可以看到不同时频分布算法实现的不同特点(This file programming the frequency spectrum of a sinusoidal FM distribution and Joy- Williams distribution, we can see by observing the time-frequency distribution of the different features of algorithm implementation)
