Greetings, I am looking for an efficeint echo cancelling algorithm, for a
telephone system.  Other requirements are minimum processing horsepower, and
a convergence time of less than 2 seconds.

                                                   thanks for any help.

                                                   phil.

You might get some useful information (and/or references) from the paper:

"An Echo Tail Canceller Based On Adaptive Interpolated FIR Filtering"
	Anis Abousaada, Tyser Aboulnasr, Willem Steenaart
IEEE Transactions on circuits and systems-II: Analog and digital signal
processing, vol. 39, No. 7, July 1992.

Good luck with it,

Andre Nieuwland
