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.
