Wiener filter based on tracking a priori SNR usingDecision-Directed method, proposed by Scalart et al 96. In this method it is assumed that SNRpost=SNRprior +1. based on this the Wiener Filter can be adapted to a model like Ephraims model in which we have a gain function which is a function of a priori SNR and a priori SNR is being tracked using Decision Directed method.

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

用分步法 计算 耦合非线性薛定谔方程； 主要用于高功率锁模增益光纤激光器的数字模拟； 模拟步骤分四步：光纤损耗传输、色散、非线性、增益； finding 是主程序，其它是函数 (Digital-to-analog simulation steps coupled nonlinear Schrö dinger equation is mainly used for high-power mode-locked gain fiber laser with a fractional step in four steps: the fiber loss transmission dispersion nonlinear gain finding is the main program, other functions)
