Abstract

If there are only one or a few strong interferers in subscriber-line transmission, Common Mode (CM) and Differential Mode (DM) show significant correlations. We extend a cancellation method already known for RFI to impulse-noise disturbance elimination. The CM provides a perfect reference to cancel impulse noise in the DM. The training of an NLMS based canceler is restricted to the impulse duration. Impulse noise can easily be detected from the CM. Fortunately, the DM signal itself couples only weakly into the CM, ensuring that the canceler will not noticeably influence the received signal.
