Abstract
A method is set forth for calculating an expected Echo Return Loss Enhancement (ERLE) in an echo canceller. The expected ERLE is used to control the adaptation step of an adaptive filter in the echo canceller. Also, a novel echo canceller is set forth where the adaptation step of its adaptive filter is controlled based on the expected ERLE.
