Channel Model Mismatch Analysis for XL-MIMO Systems from a Localization Perspective

1 code implementation30 May 2022 Hui Chen, Ahmed Elzanaty, Reza Ghazalian, Musa Furkan Keskin, Riku Jäntti, Henk Wymeersch

Radio localization is applied in high-frequency (e. g., mmWave and THz) systems to support communication and to provide location-based services without extra infrastructure.

EMF-Aware Cellular Networks in RIS-Assisted Environments

no code implementations19 Oct 2021 Hussam Ibraiwish, Ahmed Elzanaty, Yazan H. Al-Badarneh, Mohamed-Slim Alouini

The deployment of the 5th-generation cellular networks (5G) and beyond has triggered health concerns due to the electric and magnetic fields (EMF) exposure.

Green Tethered UAVs for EMF-Aware Cellular Networks

no code implementations29 May 2021 Zhengying Lou, Ahmed Elzanaty, Mohamed-Slim Alouini

Eventually, we show that TUAVs with green antennas can effectively mitigate the EMF exposure by more than 20% compared to fixed green small cells while achieving a higher data rate.

An Efficient Statistical-based Gradient Compression Technique for Distributed Training Systems

1 code implementation26 Jan 2021 Ahmed M. Abdelmoniem, Ahmed Elzanaty, Mohamed-Slim Alouini, Marco Canini

Many proposals exploit the compressibility of the gradients and propose lossy compression techniques to speed up the communication stage of distributed training.

On the Performance of Spectrum Sharing Backscatter Communication Systems

no code implementations26 Jan 2021 Yazan H. Al-Badarneh, Ahmed Elzanaty, Mohamed-Slim Alouini

Spectrum sharing backscatter communication systems are among the most prominent technologies for ultralow power and spectrum efficient communications.

When Probabilistic Shaping Realizes Improper Signaling for Hardware Distortion Mitigation

no code implementations11 Sep 2020 Sidrah Javed, Ahmed Elzanaty, Osama Amin, Basem Shihada, Mohamed-Slim Alouini

We further present a hybrid shaping (HS) design to gain the combined benefits of both PS and geometric shaping (GS).

Health Risks Associated with 5G Exposure: A View from the Communications Engineering Perspective

no code implementations1 Jun 2020 Luca Chiaraviglio, Ahmed Elzanaty, Mohamed-Slim Alouini

Finally, we examine the risk mitigation techniques based on communications engineering that can be implemented to reduce the exposure from 5G gNB and UE.
