JOINT CHANNEL FILTERING AND CREST FACTOR REDUCTION ARCHITECTURE

Abstract:

A signal processing device includes a filter, configured to receive first data representing a signal for wireless transmission, modify the first data in a filter operation, and output second data as the modified first data; a peak detector, configured to detect third data representing a peak of the signal, wherein the third data are a subset of the first data; a signal canceller, configured to receive the third data and to generate fourth data representing a cancellation signal corresponding to the peak of the signal; and a peak modifier, configured to receive the second data and the fourth data, and to generate fifth data using the second data and the fourth data, wherein the fifth data represent the signal with a modified peak.
