matlab中同步电机在abc轴系下的建模，自己用S函数编的，很好用的哦，适用于初学(synchronous motor in matlab modeling in abc shaft under its own series of S functions, good used, applies to the beginner)

最优PID控制器资料，包含matlab程序和详细的文档说明。对做pid控制的肯定有帮助( Optimal PID controller matlab program and documentation)

说明：  matlab简明教程。不用多说，要学习matlab的朋友们看看吧，基础教程。(A simple tutorial matlab. Needless to say, to learn matlab friends to see it, the basis of course.)

说明：  it is a simulation about ML synchronization algorithm in OFDM systems,you can slao see a function picture in its output,that s useful for a beginner

fixed point method of matlab

fsk调制解调matlab代码，给出了在噪声信道条件下fsk的调制和教条的matlab实现，并给出了误码率(fsk modulation and demodulation matlab code is given in the noisy channel conditions, fsk modulation and dogmatic matlab implementation, and gives the bit error rate)

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

说明：  信道编码中的典型卷积码编码算法，维特比解码方式(Channel Coding typical convolution coding algorithm, Viterbi decoding method)
