Patent ID: 7295816

Claim:
A communication system, including: a transmitter, including: an excursion signal generator configured to identify an excursion event in a first signal exceeding a threshold and generate an excursion signal corresponding to the excursion event, wherein the excursion event is comprised of a plurality of signal samples having magnitudes which exceed the threshold and wherein the first signal includes multiple channels having multiple subchannels, and the excursion signal includes corresponding channels and subchannels; and an excursion reducer responsive to the excursion signal generator and configured to subtract the excursion signal from the first signal, wherein the excursion signal subtracted from the first signal is comprised of signal samples having magnitudes which exceed the threshold, the excursion reducer including: a filter system configured to filter selected frequencies in the excursion signal; and a magnitude adjustment system configured to adjust magnitudes of the excursion signal subchannels according to magnitudes of the first signal subchannels; and a receiver configured to receive the first signal.
