ECHO CANCELLATION IN TWO-WIRE TWO-WAY DATA TRANSMISSION SYSTEMS

摘要

ECHO CANCELLATION IN TWO-WIRETWO-WAY DATA TRANSMISSION SYSTEMSAbstract of the DisclosureAn adaptive echo canceller for two-wire simul-taneous two-way data communication at full bandwidthuses Nyquist-interval, rather than baud-interval,processing to achieve independence from timingdiscrepancies between near-end and far-end terminals.The entire echo signal, and not merely baud-intervalsamples thereof, is suppressed. The echo cancelleris preferably a transversal structure.
