Gaussian-lognormal-distribution

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.

程序相当有用，可用于数学建模中。数据是实例，程序浅显易懂。(Program is useful for mathematical modeling. Data instance, the program easy to understand.)
