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…
Privacy-Preserving Wireless Federated Learning Exploiting Inherent Hardware Impairments
Sina Rezaei Aghdam, Ehsan Amid, Marija Furdek +1
We consider a wireless federated learning system where multiple data holder edge devices collaborate to train a global model via sharing their parameter updates with an honest-but-…
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…
Learning End-to-End Codes for the BPSK-constrained Gaussian Wiretap Channel
Alireza Nooraiepour, Sina Rezaei Aghdam
Finite-length codes are learned for the Gaussian wiretap channel in an end-to-end manner assuming that the communication parties are equipped with deep neural networks (DNNs), and…
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…
