Abstract:
Systems and methods for digital predistortion (DPD) are disclosed herein. In an example embodiment, a digital front-end circuit includes a DPD block, power amplifier, and transmitter. The DPD block is configured to receive an input signal and to provide a first output signal, and includes a nonlinear model that is configured to generate a nonlinear model output signal based upon the input signal. The DPD block additionally includes a first mixing module that is configured to generate a mixing module output signal based upon the input signal and the nonlinear model output signal. The DPD block further includes a summation block that is configured to generate the first output signal at least in part as a first sum of the nonlinear model output signal and the mixing module output signal, and the first mixing module includes a plurality of first finite impulse response (FIR) filters.
