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…
Timing and Frequency Synchronization for 1-bit Massive MU-MIMO-OFDM Downlink
Sven Jacobsson, Carl Lindquist, Giuseppe Durisi +2
We consider timing and frequency synchronization for the massive multiuser (MU) multiple-input multiple-output (MIMO) downlink where 1-bit digital-to-analog converters (DACs) are u…
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…
