Underwater Multi-Wavelength Optical Links With Blue Targets and Constraints: Opportunities and Challenges
Alain R. Ndjiongue, Octavia A. Dobre, Hyundong Shin +1
Underwater optical wireless technologies offer multiple advantages over the acoustic technology. Acoustic signals, for instance, are susceptible to noise from marine sources due to…
Maximal Transmission Rate in Omni-DRIS-Assisted Indoor Visible Light Communication Systems
Alain R. Ndjiongue, Octavia A. Dobre, Hyundong Shin
Given the importance of reconfigurable intelligent surfaces (RISs) in next-generation mobile systems, several RIS variants have been proposed in recent years. Omni-digital-RIS (omn…
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…
Towards the Use of Re-configurable Intelligent Surfaces in VLC Systems: Beam Steering
Alain R. Ndjiongue, Telex M. N. Ngatched, Octavia A. Dobre +1
The emergence of visible light communication (VLC) technology as a solution to solve radio frequency impediments, such as spectrum shortage, is continuously appealing. In addition…
