A digital predistortion technique based on a NARX network to linearize GaN class F power amplifiers
(2014)
This work presents a novel Digital Predistortion (DPD) scheme based on a NARX network, suitable for linearizing power amplifiers (PAs). The NARX network is a Recurrent Neural Network (RNN) with embedded memory that allows ...
