Digital RIS (DRIS): The Future of Digital Beam Management in RIS-Assisted OWC Systems
Alain R. Ndjiongue, Telex M. N. Ngatched, Octavia A. Dobre +1
Reconfigurable intelligent surfaces (RIS) have been recently introduced to optical wireless communication (OWC) networks to resolve skip areas and improve the signal-to-noise ratio…
Design of a Power Amplifying-RIS for Free-Space Optical Communication Systems
Alain R. Ndjiongue, Telex M. N. Ngatched, Octavia A. Dobre +1
The steering dynamics of re-configurable intelligent surfaces (RIS) have hoisted them to the front row of technologies that can be exploited to solve skip-zones in wireless communi…
Performance Analysis of RIS-Based nT-FSO Link Over G-G Turbulence With Pointing Errors
Alain R. Ndjiongue, Telex M. N. Ngatched, Octavia A. Dobre +2
One of the main problems faced by communication systems is the presence of skip-zones in the targeted areas. With the deployment of the fifth-generation mobile network, solutions a…
Re-configurable Intelligent Surface-based VLC Receivers Using Tunable Liquid-crystals: The Concept
Alain R. Ndjiongue, Telex M. N. Ngatched, Octavia A. Dobre +1
Visible light communication (VLC) enables access to huge unlicensed bandwidth, a higher security level, and no radio frequency interference. With these advantages, VLC emerges as a…
