Abstract:
1. A signal processing system, comprising: an excursion signal generator configured to identify an excursion in a first signal exceeding a signal magnitude threshold and generate a corresponding excursion signal, wherein the excursion signal comprises one or more excursion events, each of which may comprise multiple peak events, and wherein the first signal comprises one or more channel signals transmitted via one or more channels, an excursion signal scaling system configured to adjust the magnitude of the excursion signal, an excursion filter system configured to filter selected frequencies from the scaled excursion signal, a channel scaling system configured to vary the scaling of at least one of the channel signals comprising the excursion signal based on a channel signal quality, wherein the channel scaling system is configured to determine the channel signal quality and adaptively adjust the gain of at least one of the channel signals based on the determination, and an excursion reducer configured to subtract the scaled, filtered and gain-adjusted excursion signal from a suitably delayed version of the first signal.
