Abstract
Disclosed are methods, systems, devices, apparatus, media, and other implementations, including a method for digital predistortion for a power amplifier system. The method includes determining one or more system characteristics for the power amplifier system comprising at least a power amplifier that produces output with non-linear distortions, with the one or more system characteristics corresponding to an estimate for a complex load metric for the power amplifier system coupled to a load. The method further includes determining, based on the one or more system characteristics corresponding to the estimate for the complex load metric, digital predistortion (DPD) coefficients to compensate for the nonlinear behavior of the power amplifier system.
