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…
Reconfigurable Intelligent Surface Optimization for Uplink Sparse Code Multiple Access
Ibrahim Al-Nahhal, Octavia A. Dobre, Ertugrul Basar +2
The reconfigurable intelligent surface (RIS)-assisted sparse code multiple access (RIS-SCMA) is an attractive scheme for future wireless networks. In this letter, for the first tim…
Deep Reinforcement Learning for Optimizing RIS-Assisted HD-FD Wireless Systems
Alice Faisal, Ibrahim Al-Nahhal, Octavia A. Dobre +1
This letter investigates the reconfigurable intelligent surface (RIS)-assisted multiple-input single-output (MISO) wireless system, where both half-duplex (HD) and full-duplex (FD)…
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…
Incremental Relaying for Power Line Communication: Performance Analysis and Power Allocation
Ankit Dubey, Chinmoy Kundu, Telex M. N. Ngatched +2
In this paper, incremental decode-and-forward (IDF) and incremental selective decode-and-forward (ISDF) relaying are proposed to improve the spectral efficiency of power line commu…
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…
