MCRB-based Performance Analysis of 6G Localization under Hardware Impairments
Hui Chen, Sina Rezaei Aghdam, Musa Furkan Keskin +6
Location information is expected to be the key to meeting the needs of communication and context-aware services in 6G systems. User localization is achieved based on delay and/or a…
Piecewise Digital Predistortion fo mmWave Active Antenna Arrays: Algorithms and Measurements
Alberto Brihuega, Mahmoud Abdelaziz, Lauri Anttila +4
In this paper, we describe a novel framework for digital predistortion (DPD) based linearization of strongly nonlinear millimeter-wave active antenna arrays. Specifically, we formu…
Linearizing Active Antenna Arrays: Method and Measurements
Alberto Brihuega, Mahmoud Abdelaziz, Matias Turunen +3
In this paper, we provide a novel framework for efficient digital predistortion (DPD) based linearization of active antenna arrays with multiple and mutually different nonlinear po…
Distortion-Aware Linear Precoding for Millimeter-Wave Multiuser MISO Downlink
Sina Rezaei Aghdam, Sven Jacobsson, Thomas Eriksson
In this work, we propose an iterative scheme for computing a linear precoder that takes into account the impact of hardware impairments in the multiuser multiple-input single-outpu…
Digital Predistortion for Multiuser Hybrid MIMO at mmWaves
Alberto Brihuega, Lauri Anttila, Mahmoud Abdelaziz +2
Efficient mitigation of power amplifier (PA) nonlinear distortion in multi-user hybrid precoding based broadband mmWave systems is an open research problem. In this article, we fir…
Millimeter-Wave Over-the-Air Signal-to-Interference-plus-Noise-Ratio Measurements Using a MIMO Testbed
Koen Buisman, David Cheadle, Tian Hong Loh +2
In this paper, over-the-air experiments with external and internal interferences were performed using Chalmers millimeter-wave multiple-input-multiple-output testbed MATE. The resu…
