Abstract
Exemplary embodiments are related to power amplifier power level compensation in a pre-distortion system. A method may include applying digital pre-distortion (DPD) of a power amplifier at a frequency channel, a fixed input power value, and a fixed temperature. The method may also include determining an optimal input power value for the power amplifier in response to a change in at least one of frequency and temperature.
