Abstract
Official abstract text for this publication.
A packet voice transceiver adapted to reside at a first end of a communication network and to send an ingress communication signal comprising voice packets to, and receive an egress communication signal comprising voice packets from, a second packet voice transceiver residing at a second end of the communication network. The packet voice transceiver includes a far-end echo canceller that reduces echo that is present in the egress communication signal. The far-end communicates with other functional components of the transceiver system and cancels echo or refrains from canceling echo based on the activity of the other functional components.
First claim
Opening claim text (preview).
What is claimed is: 1. A packet voice transceiver, comprising: circuitry configured to identify an unreceived data element in an inbound communication signal; and estimate a parameter of the unreceived data element, where echo cancellation of the inbound communication signal is bypassed during estimation of the parameter of the unreceived data element. 2. The packet voice transceiver of claim 1 , wherein the circuitry is configured to cancel echo that i…
