A doubletalk detector for critically sampled subband adaptive echo cancellers

Abstract

This paper describes a novel cross-correlation-based doubletalk detection algorithm derived for use in individual subbands of a critically sampled subband echo canceller. In addition, each per-subband doubletalk detector is allowed to control adaptation of its corresponding adaptive filter independently in response to doubletalk conditions. Simulation… (More)
