Patent ID: 6965657

Claim:
A system for suppressing interference in a communication of data channels across a common communication medium and the system for suppressing interference comprising: a remote set of modems coupled to a remote end of the common communication medium; a local set of modems coupled to a local end of the common communication medium; and an interference canceller coupled with the local set of modems and configured to coordinate during a training phase, transmissions of selected interfering data channels of at least the remote set of modems with reception of at least one selected victim data channel at a corresponding one of the local set of modems and to adaptively derive at least far end crosstalk (FEXT) interference cancellation coefficients between the at least one victim data channel and the selected interfering data channels and to apply the interference cancellation coefficients during a runtime phase to communications received by the corresponding one of the local set of modems to substantially cancel at least FEXT interference therein.
