Patent ID: 7688968

Claim:
An adaptive analog echo/near-end crosstalk (NEXT) cancellation system, comprising: a selector that selects between a first mode and a second mode in response to a mode select signal, wherein said selector: outputs, during said first mode, a first error control signal that is based on first interference in a first receive signal, wherein said first mode corresponds to when said first receive signal does not include a remotely transmitted signal, and outputs, during said second mode, a second error control signal that is based on second interference in a second receive signal following said first mode when said second receive signal includes said remotely transmitted signal; and an echo/NEXT cancellation module that communicates with said selector and that generates an estimated echo/NEXT signal, wherein said estimated echo/NEXT signal is adjusted by said first error control signal and a first transmit signal when said first receive signal does not include said remotely transmitted signal, and adjusted by said second error control signal and said first transmit signal when said second receive signal includes said remotely transmitted signal.
