When Distortion Helps: Secure GNN Precoding with Nonlinear Power Amplifiers
Reza Ghasemi Alavicheh, Thomas Feys, Md Arifur Rahman +1
Physical layer security (PLS) provides information-theoretic protection against eavesdropping. While existing techniques assume ideal linear transmitters, power amplifiers (PAs) in…
An Open-Source Hardware-Aware Sub-THz Radio-Stripe Simulator
Tijl Schepens, Thomas Feys, Thomas Eriksson +1
Sub-Terahertz radio-stripe and distributed MIMO architectures promise extreme spatial reuse and multi-GHz bandwidths, but the cascaded fiber front-haul and RF hardware impairments…
Testbed Evaluation of AI-based Precoding in Distributed MIMO Systems
Tianzheng Miao, Thomas Feys, Gilles Callebaut +3
Distributed MIMO (D-MIMO) has emerged as a key architecture for future sixth-generation (6G) networks, enabling cooperative transmission across spatially distributed access points…
The environmental impact of ICT in the era of data and artificial intelligence
François Rottenberg, Thomas Feys, Liesbet Van der Perre
The technology industry promotes artificial intelligence (AI) as a key enabler to solve a vast number of problems, including the environmental crisis. However, when looking at the…
Learning to Quantize and Precode in Massive MIMO Systems for Energy Reduction: a Graph Neural Network Approach
Thomas Feys, Liesbet Van der Perre, François Rottenberg
Massive MIMO systems are moving toward increased numbers of radio frequency chains, higher carrier frequencies and larger bandwidths. As such, digital-to-analog converters (DACs) a…
Leveraging Power Amplifier Distortion for Physical Layer Security
Reza Ghasemi Alavicheh, Thomas Feys, MD Arifur Rahman +1
This paper introduces a new approach to physical layer security (PLS) by leveraging power amplifier (PA) nonlinear distortion through distortion-aware precoding. While some convent…
