Digital Cancellation of Passive Intermodulation in FDD Transceivers
Muhammad Zeeshan Waheed, Pablo Pascual Campo, Dani Korpi +3
Modern radio systems and transceivers utilize carrier aggregation (CA) to meet the demands for higher and higher data rates. However, the adoption of CA in the existing Long Term E…
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…
