Abstract: A transmitter comprises a first peak-to-average-power ratio (PAPR) suppression circuit and a second peak-to-average-power ratio (PAPR) suppression circuit. The first PAPR suppression circuit may receive a first sequence of time-domain symbols to be transmitted, alter the first sequence based on each of a plurality of symbol ordering and/or inversion descriptors to generate a corresponding plurality of second sequences of time-domain symbols, measure a PAPR corresponding to each of the second sequences, select one of the plurality of symbol ordering and/or inversion descriptors based on the measurement of PAPR, and convey the selected one of the symbol ordering and/or inversion descriptors to the second PAPR suppression circuit. The second PAPR suppression circuit may receive the first sequence of time-domain symbols to be transmitted, and alter the first sequence based on the selected one of the symbol ordering and/or inversion descriptors to generate a reordered and/or inverted symbol sequence.

Abstract: Systems and methods are provided for band-limited digital pre-distortion (DPD) expansion estimation and curve adjustment. Pre-distortion adjustments may be applied during processing of an input signal, and expansion introduced as result of applying the pre-distortion adjustments may then be estimated. Expansion adjustments may then be determined based on the estimated expansion, and the expansion adjustments may be applied in a feedback manner during subsequent processing operations.
