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.

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).

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.

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.

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.

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.

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.

Joint Uplink and Downlink EMF Exposure: Performance Analysis and Design Insights

no code implementations9 Feb 2023 Lin Chen, Ahmed Elzanaty, Mustafa A. Kishk, Luca Chiaraviglio, Mohamed-Slim Alouini

Tuning the system parameters such as the BS density and the minimum distance from a BS to restricted areas, we show a trade-off between reducing the population's exposure to EMF and enhancing the network coverage performance.

MU-Massive MIMO with Multiple RISs: SINR Maximization and Asymptotic Analysis

no code implementations7 Mar 2023 Somayeh Aghashahi, Zolfa Zeinalpour-Yazdi, Aliakbar Tadaion, Mahdi Boloursaz Mashhadi, Ahmed Elzanaty

In this letter, we investigate the signal-to-interference-plus-noise-ratio (SINR) maximization problem in a multi-user massive multiple-input-multiple-output (massive MIMO) system enabled with multiple reconfigurable intelligent surfaces (RISs).

Near and Far Field Model Mismatch: Implications on 6G Communications, Localization, and Sensing

no code implementations10 Oct 2023 Ahmed Elzanaty, Jiuyu Liu, Anna Guerra, Francesco Guidi, Yi Ma, Rahim Tafazolli

The upcoming 6G technology is expected to operate in near-field (NF) radiating conditions thanks to high-frequency and electrically large antenna arrays.

ELAA Near-Field Localization and Sensing with Partial Blockage Detection

no code implementations24 Feb 2024 Hui Chen, Pinjun Zheng, Yu Ge, Ahmed Elzanaty, Jiguang He, Tareq Y. Al-Naffouri, Henk Wymeersch

Considering the array size could be much larger than an obstacle, the effect of partial blockage (i. e., a portion of antennas are blocked) is investigated, and a blockage detection algorithm is proposed.
