Neural Network-Based Nonlinear Interpolation for Digital Predistortion With Bandlimited Feedback for Wideband Power Amplifiers
Transmitter linearization through digital predistortion (DPD) typically relies on a dedicated wideband, high sampling-rate feedback receiver. These dedicated receivers are expensive and consume significant power. To address this challenge, we propose a neural network (NN)-based nonlinear interpolator that reconstructs...
