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.

说明：  this code is important
