% [w,y,e,p]= asptleakynlms(x,w,d,mu,a,p,b)
%% Performs filtering and coefficient update using the
% Leaky Normalized Least Mean Squares algorithm. The
% update equation is given by
% w(n) = a * w(n-1) + mu * e(n) x(n)
% % Input Parameters [Size]:: % x : input samples delay line [L x 1]
% w : filter coefficients vector w(n-1) [L x 1]
% d : desired output d(n) [1 x 1]
% mu : adaptation constant
% a : leak factor (0 < a < 1)% p : last estimated power of x p(n-1)
% b : AR pole for recursive calculation of p% Output parameters::
% w : updated filter coefficients w(n)
% y : filter output y(n)
% e : error signal; e(n) = d(n)-y(n)
% p : new estimated power of x p(n)
