说明：  plotHHT为一个绘制信号希尔伯特谱的程序，主要为希尔伯特黄变换。(PlotHHT is a program for plotting Hilbert spectrum of signals, which is mainly Hilbert Huang transform.)

精通matlab7混合编程电子书，此书很经典，供大家参考(Proficient matlab7 hybrid programming books, this book is classic, for your reference)

compute the Independent component analysis (ICA) with the algorithm of infomax

I,Q通道的 噪声过程是高斯的的,而且是互不相关的,他的功率谱也是白的. 因为I和Q通道的噪声过程是高斯的,而且是互不相关的 我们可以得到他们是相互独立(Papoulis,1984). 最后,由于I和Q通道是独立的零均值高斯过程,因此可以推导出:复信号:I+jQ,幅度是瑞丽分布的,幅度的平放是指数分布的,相位角arctan(Q/I)是在(0,2π]上均匀分布(I Q Gaussian noise)
