can anyone help in designing a decorrelation filter? - kundan burnwal - Mar 12 9:26:00 2005




hi,
can anyone help me in using levinson-durbin alg. for
decorrelation a speech signal? or is their some other
technique to decorrelate a signal? i searched the net
but couldn't find anything useful.

i want to decorrelate the speech signal before passing
it to nlms block in acoustic feedback cancellation in
order to decrease the convergence time of adaptive
filter used for feedback cancellation in lecture room.

thanks n regards,
kundan __________________________________
