摘要
This document discloses one or more systems, apparatuses, methods, etc. for implementing an echo cancellation algorithm for long delayed echo that is created during a wire or wireless voice communications. In an implementation, a WiDi feature in a device during the wire or wireless voice communications may add an additional echo delay in addition to channel multipath delay when an audio sound signal travels from a WiDi component to a microphone of the device. In this implementation, a separate delay estimator is configured to estimate total delay. The estimated total delay is fed back to an adoptive filter component for long delay echo cancellation.
