fit_ML_rayleigh - Maximum Likelihood fit of the rayleigh distribution of i.i.d. samples!. Given the samples of a rayleigh distribution, the PDF parameter is found fits data to the probability of the form: p(r)=r*exp(-r^2/(2*s))/s with parameter: s format: result = fit_ML_rayleigh( x,hAx ) input: x - vector, samples with rayleigh distribution to be parameterized hAx - handle of an axis, on which the fitted distribution is plotted if h is given empty, a figure is created. output: result - structure with the fields s - fitted parameter CRB - Cram?r-Rao Bound for the estimator value RMS - RMS error of the estimation type- ML

说明：  ：抽取是软件无线电中最核心部分。通过对多项抽取结构的分析，设计出一种多 级抽取滤波器的实现方案，并通过MATLAB仿真实现。 关键词：软件无线电；多相结构；多级抽取滤波器(: Extraction is the most central part of the software radio. By taking a number of structural analysis, design a multi-stage decimation filter implementation scheme, and Simulation by MATLAB. Key words: software radio heterogeneous structure multi-stage decimation filter)
