Comparison of echo cancellation algorithms for the adaptive delay filter

Abstract

Three algorithms for use with the adaptive delay filter structure are presented and compared. The three algorithms are: the maximum deviation from repression line algorithm, the delay selection from variance threshold algorithm, and the delay selection from cross-covariance algorithm. The performance of these algorithms in system modeling of a multipath echo cancellation environment is compared under various assumptions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
