Modeling and Analysis of OFDM-based 5G/6G Localization under Hardware Impairments
Hui Chen, Musa Furkan Keskin, Sina Rezaei Aghdam +6
Localization is envisioned as a key enabler to satisfy the requirements of communication and context-aware services in the fifth/sixth generation (5G/6G) communication systems. Use…
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…
Discrete-time models and performance of phase noise channels
Amina Piemontese, Giulio Colavolpe, Thomas Eriksson
This paper deals with the phase noise affecting communication systems, where local oscillators are employed to obtain reference signals for carrier and timing synchronizations. The…
Distortion-Aware Linear Precoding for Massive MIMO Downlink Systems with Nonlinear Power Amplifiers
Sina Rezaei Aghdam, Sven Jacobsson, Ulf Gustavsson +3
We introduce a framework for linear precoder design over a massive multiple-input multiple-output downlink system in the presence of nonlinear power amplifiers (PAs). By studying t…
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…
