1. A system for linearizing a power amplifier through digital predistortion, comprising processing circuitry configured to: obtain an input signal sample that depends on an input signal to the power amplifier; predistort the input signal sample using a static weight function to generate a first intermediate predistorted signal sample; predistort the same input signal sample using a dynamic weight function to generate a second intermediate predistorted signal sample; combine additively the first intermediate predistorted signal sample and the second intermediate predistorted signal sample together to obtain an output signal sample of the predistorter.
