两个重要文件： 1、Rayleigh_Doppler_singlePath.m 产生单径Rayleigh衰落，采用了6种方法并进行了比较，推荐使用第6种方法； 2、Rayleigh_Doppler_multiPath.m 根据多条径的延时和强度，产生频率选择性衰落； 在单径和多径两个程序中，均提供了其功率谱的输出代码； (Two important documents: 1, Rayleigh_Doppler_singlePath.m to generate a single path Rayleigh fading, using six kinds of ways and compared, 6 recommended methods 2, Rayleigh_Doppler_multiPath.m under a number of path delay and intensity, resulting in frequency selective fading in both single path and multi-path process, provide the output of its power spectrum code )

原来先进PID控制MATLAB仿真中大林控制算法有较大的错误，这是我经过修改在MATLAB7.11.0上调试成功后的代码。(Original Advanced PID control MATLAB simulation the Dalin control algorithm with larger error This is the modified code debugging success)

these operators can be used for segmentation

fit_rayleigh_pdf - Non Linear Least Squares fit of the Rayleigh distribution. given the samples of the histogram of the samples, finds the distribution parameter that fits the histogram samples.fits data to the probability of the form: p(r)=r*exp(-r^2/(2*s))/s with parameter: s format:result = fit_rayleigh_pdf( x,y,W,hAx ) input: y - vector, samples of the histogram to be fitted x - vector, position of the samples of the histogram (i.e. y = f(x,a)) W - matrix or scalar, a square weighting matrix of the size NxN where N = length(y), or 0 to indicate no weighting is needed. hAx - handle of an axis, on which the fitted distribution is plotted output: result - structure with the fields s - fitted parameter VAR - variance of the estimation type- weighted LS or not weighted LS iter- number of iteration for the solution
