摘要: A method and apparatus for cancelling self-interference in a cable network implementing full duplex (FDX). processor modem may obtain frequency response of an echo channel at least one sub-channel FDX band calculate filter coefficients based on the response, interference canceller cancels downstream signal. The includes filters digital domain to generate cancellation signal from reference In another example, responses all sub-channels band, combine impulse combined response. then cancel analog
