Orthogonalized power filters for nonlinear acoustic echo cancellation

Abstract

Standard approaches for the cancellation of acoustic echoes in telecommunication systems assume that the echo path to be identified can be modeled by a linear system. However, in applications such as echo cancellation for mobile communication terminals, non-negligible nonlinear distortions are introduced by loudspeakers and their amplifiers, resulting in a… (More)
