Reliable ORIS-assisted FSO Communications via HARQ
Georgios D. Chondrogiannis, Athanasios P. Chrysologou, Vasilis K. Papanikolaou +3
This paper studies a free-space optical (FSO) link assisted by an optical reconfigurable intelligent surface (ORIS) and enhanced by a hybrid automatic repeat request (HARQ) scheme.…
Optical RIS-enabled Multiple Access Communications
Georgios D. Chondrogiannis, Athanasios P. Chrysologou, Alexandros-Apostolos A. Boulogeorgos +2
In this paper, we identify optical reconfigurable intelligent surfaces (ORISs) as key enablers of next-generation free-space optical (FSO) multiple access systems. By leveraging th…
Power-Optimal HARQ Protocol for Reliable Free Space Optical Communication
Georgios D. Chondrogiannis, Nikos A. Mitsiou, Nestor D. Chatzidiamantis +2
This paper investigates the usage of hybrid automatic repeat request (HARQ) protocols for power-efficient and reliable communications over free space optical (FSO) links. By exploi…
