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…
Performance Analysis of ARQ-based RF-FSO Links
Behrooz Makki, Tommy Svensson, Thomas Eriksson +1
In this letter, we study the performance of hybrid radio-frequency (RF) and free-space optical (FSO) links using automatic repeat request (ARQ). We derive closed-form expressions f…
Varactor-Based Dynamic Load Modulation of High Power Amplifiers
Ali Soltani Tehrani, Hossein Mashad Nemati, Haiying Cao +2
In this work, dynamic load modulation of high power amplifiers using a varactor-based tunable matching network is presented. The feasibility of dynamic tuning and efficiency enhanc…
