Digital Predistortion in Large-Array Digital Beamforming Transmitters [PDF]
2018 52nd Asilomar Conference on Signals, Systems, and Computers, 2018 In this article, we propose a novel digital predistortion (DPD) solution that allows to considerably reduce the complexity resulting from linearizing a set of power amplifiers (PAs) in single-user large-scale digital beamforming transmitters. In contrast

Frequency-Domain Digital Predistortion for OFDM
IEEE Microwave and Wireless Components Letters, 2021 In this letter, a novel frequency-domain (FD) digital predistortion (DPD) solution for orthogonal frequency division multiplexing (OFDM) transmitters (TXs) is proposed. The proposed approach allows to flexibly control the linearization performance, in FD, such that different degrees of linearization can be provided at different parts of the spectrum ...
