Abstract
Systems and methods are disclosed for providing band-limited power amplifier linearization. In one embodiment, a system includes a power amplifier configured to amplify a power amplifier input signal to provide a power amplifier output signal and a digital predistortion system configured to compensate for up to a predefined maximum order of non-linearity of the power amplifier. The digital predistortion system includes a band-limited adaptation subsystem. As compared to conventional adaptation subsystems, the band-limited adaptation subsystem is significantly less complex and consumes less power.
