Help on ERLE - ganesa1234 - Sep 7 8:02:00 2004



Dear Guys

I am Ganesh, and i would like to ask you'll a question on erle.

I calculate ERLE as described below:

Pd=filter(1,[1, -0.98],d.^2);
Pe=filter(1,[1, -0.98],e.^2);
erle=10*log10(Pd/Pe)

I am trying to calculate erle in Matlab, but by using the above
method, i dont get a proper value at all.

I would like some help from you'll on whether that is the right
method to calculate ERLE, or are there any other method.

Hope to hear from you'll soon.

Regards

Ganesh
