Comparative Study of Real-Time Beamforming Techniques for Railway Communication Systems in LoS and NLoS Scenarios

Semah Mabrouki, Iyad Dayoub, Marion Berbineau

This paper presents a comparative study of real-time beamforming techniques for railway communication systems in Line-of-Sight (LoS) and Non-Line-of-Sight (NLoS) scenarios. Using the 3GPP TR 38.901 channel model, initial machine learning (ML)-based beam prediction solutions are evaluated, and…

Joint Sub-6 GHz and mm-Wave V2I MIMO Radio Channel Characterization

Pascal Pagani, Pierre Laly, Eric Simon, Valentin Picquet, Raffaele d'Errico, Davy Gaillot

The development of 5G and 6G networks has driven to the development of two key technologies: massive Multiple-Input Multiple-Output (mMIMO) and access to millimeter wave (mm-Wave) frequencies [1], and the concept of distributed cell-free massive MIMO (CF-mMIMO), primarily targeting sub-6GHz…

Realistic EMF Exposure Estimation from Low Density Sensor Network by Finite & Infinite Neural Networks

M. Mallik, Laurent Clavier, Davy Gaillot

Understanding the spatial and temporal patterns of environmental exposure to radio-frequency electromagnetic fields (RF - EMF) is essential for conducting risk assessments. These assessments aim to explore potential connections between RF-EMF exposure and its effects on human health, as well as on…

Theoretical study of randomly distributed gold nanoparticles as potential plasmonic physically unclonable functions

Ophélie Saison-Francioso, Gaëtan Lévêque, Yan Pennec, Abdellatif Akjouj

We theoretically study a random arrangement of cylindrical gold nanoparticles (NPs) deposited on a dielectric/gold substrate as a potential plasmonic physically unclonable function (PUF). We use the coupled dipole approximation (CDA) method in order to reduce the computation time and memory demand…
