Non-Uniform Codebook Design for Optical IRS-Assisted VLC Systems
Rashid Iqbal, Dimitrios Bozanis, Dimitrios Tyrovolas +4
Optical intelligent reflecting surfaces (OIRS) can improve the coverage of indoor visible light communication (VLC) systems, however, practical deployment requires a finite offline…
Enabling mmWave Communications with VCSEL-Based Light-Emitting Reconfigurable Intelligent Surfaces
Rashid Iqbal, Dimitrios Bozanis, Dimitrios Tyrovolas +4
This paper proposes a light-emitting reconfigurable intelligent surface (LeRIS) architecture that integrates vertical cavity surface-emitting lasers (VCSELs) to jointly support use…
A Scanning-Based Indoor Optical Wireless Positioning System with Single VCSEL
Yicheng Dong, Rashid Iqbal, Julien Le Kernec +1
This paper presents a novel indoor visible light positioning (VLP) system utilising one vertical-cavity surface-emitting laser installed at the ceiling centre of a space. The syste…
Enhancing PLS of Indoor IRS-VLC Systems for Colluding and Non-Colluding Eavesdroppers
Rashid Iqbal, Ahmed Zoha, Salama Ikki +2
Most intelligent reflecting surface (IRS)-aided indoor visible light communication (VLC) studies ignore the time delays introduced by reflected paths, even though these delays are…
Integrated Localization, Mapping, and Communication through VCSEL-Based Light-emitting RIS (LeRIS)
Rashid Iqbal, Dimitrios Bozanis, Dimitrios Tyrovolas +5
Light-emitting reconfigurable intelligent surfaces (LeRISs) have recently emerged as a promising solution for providing the spatial awareness required for reliable millimeter-wave…
Leveraging IRS Induced Time Delay for Enhanced Physical Layer Security in VLC Systems
Rashid Iqbal, Mauro Biagi, Ahmed Zoha +2
Indoor visible light communication (VLC) is considered secure against attackers outside the confined area where the light propagates, but it is still susceptible to interception fr…
