Digital Predistortion in Large-Array Digital Beamforming Transmitters
Alberto Brihuega, Lauri Anttila, Mahmoud Abdelaziz +1
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…
Performance Comparison of Constant Envelope and Zero-forcing Precoders in Multiuser Massive MIMO
Alberto Brihuega, Lauri Anttila, Mikko Valkama
In this article, the adoption and performance of a constant envelope (CE) type spatial precoder is addressed in large-scale multiuser MIMO based cellular network. We first formulat…
Digital Predistortion for Hybrid MIMO Transmitters
Mahmoud Abdelaziz, Lauri Anttila, Alberto Brihuega +2
This article investigates digital predistortion (DPD) linearization of hybrid beamforming large-scale antenna transmitters. We propose a novel DPD processing and learning technique…
