Echo Return Loss Enhancement(ERLE)

Started by ganesa1234 September 6, 2004
Dear Guys I am having some problem in calculating the ERLE for my
simulations. Below is the code that i use to calculate the ERLE.

% Pd=filter(1,[1, -0.98],d.^2);
% Pe=filter(1,[1, -0.98],e.^2);

% erle*log10(Pd./Pe)

e = error
d = different's in the actual speech and the predicted speech But i do not get a good erle. I just would like someone to confirm
whether this is the right way to calculate the ERLE, or are the any
other method to calculate ERLE.

Hope to hear from you'll soon.

Regards

Ganesh
