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
