Rayleigh_vir

计算数独的好方法，能够快速解决问题，使用方便(Good way to calculate the number of independent, able to quickly solve the problem, easy to use)

仿真了地球杂波的情况。考虑了地球自转带来的多普勒旋转等影响。仿真结果和理论相一致。可作为星载雷达地球杂波仿真的参考(Clutter simulation in the case of the Earth. Taking into account the Earth' s rotation brought about by the impact of Doppler rotation. Simulation results and theoretical line. Can be used as space-borne radar clutter simulation of the Earth' s reference)

This is BER simulation source file with matlab.bpsk, qpsk, 16qam

说明：  FFT地址倒置Matlab程序，可通过调用得到2的N次方地址倒置(m code)

现代通信系统仿真中锁相环仿真的PLL前处理程序(Modern communication systems simulation of the PLL phase-locked loop simulation procedures before)

Compiled database of musical notes for use in Matlab

说明：  不用直接调用函数的canny算子的matlab源码，可以直接运行产生结果。(Without directly calling functions canny operator matlab source code, can run to produce results.)

直接扩频信号抑制正弦干扰效果，横坐标为信噪比，纵坐标为误码率(restrain of sinusoidal interference in ds_ss signal)

MIMO系统误码率随接受天线数目变化而变化，MATLAB仿真程序，源代码(MIMO system bit error rate with the number of antennas to accept changes, MATLAB simulation program, the source code)

fit_maxwell_pdf - Non Linear Least Squares fit of the maxwellian 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) = sqrt(2/pi)*(a^(-3/2))*(r^2)*exp(-(r^2)/(2*a)) with parameter: a format: result = fit_maxwell_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 if h is given empty, a figure is created. output: result - structure with the fields a - fitted parameter VAR - variance of the estimation type- weighted LS or not weighted LS iter- number of iteration for the solution
