Abstract
Various examples are directed to systems and methods for wideband digital predistortion. A digital pre-distortion circuit may be programmed to receive a complex baseband signal and generate a pre-distorted signal. Generating the pre -distorted signal may comprise applying to the complex baseband signal a first correction for an Nth order distortion of a power amplifier at an Ith harmonic frequency zone centered at about an Ith harmonic of a carrier frequency and applying to the complex baseband signal a second correction for the Nth order distortion at a Jth harmonic frequency zone centered at about a Jth harmonic of the carrier frequency different than the Ith harmonic of a carrier frequency.
