Optical Wireless Cochlear Implants
Stylianos E. Trevlakis, Alexandros-Apostolos A. Boulogeorgos, Paschalis C. Sofotasios +2
In the present contribution, we introduce a wireless optical communication-based system architecture which is shown to significantly improve the reliability and the spectral and po…
Wireless Terahertz System Architectures for Networks Beyond 5G
Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou, Dimitrios Kritharidis +15
The present white paper focuses on the system requirements of TERRANOVA. Initially details the key use cases for the TERRANOVA technology and presents the description of the networ…
Low-cost Cognitive Radios against Spectrum Scarcity
Alexandros-Apostolos A. Boulogeorgos, George K. Karagiannidis
The next generation wireless networks are envisioned to deal with the expected thousand-fold increase in total mobile broadband data and the hundred-fold increase in connected devi…
Physical Layer Security in the Presence of Interference
Dimitrios S. Karas, Alexandros-Apostolos A. Boulogeorgos, George K. Karagiannidis
We evaluate and quantify the joint effect of fading and multiple interferers on the physical-layer (PHY) security of a system consisted of a base-station (BS), a legitimate user, a…
Spectrum Sensing with Multiple Primary Users over Fading Channels
Alexandros-Apostolos A. Boulogeorgos, Nestor D. Chatzidiamantis, George K. Karagiannidis
We investigate the impact of multiple primary users (PUs) and fading on the spectrum sensing of a classical energy detector (ED). Specifically, we present novel closed-form express…
Terahertz Technologies to Deliver Optical Network Quality of Experience in Wireless Systems Beyond 5G
Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou, Thomas Merkle +11
This article discusses the basic system architecture for terahertz (THz) wireless links with bandwidths of more than 50 GHz into optical networks. New design principles and breakth…
