Brain-Inspired User Positioning for mmWave Beam Management
Aris Karampelas Timotijevic, Evangelos Koutsonas, Vasileios Kouvakis +3
Wireless positioning is a key enabling functionality of high-frequency, highly directional wireless systems. Supporting beam tracking depends on accurately translating channel stat…
Dual-Graph Multi-Agent Reinforcement Learning for Handover Optimization
Matteo Salvatori, Filippo Vannella, Sebastian Macaluso +5
HandOver (HO) control in cellular networks is governed by a set of HO control parameters that are traditionally configured through rule-based heuristics. A key parameter for HO opt…
Waveform Design for Partial-Time Superimposed ISAC Systems
Xi Nan, Rugui Yao, Ye Fan +4
Nowadays, waveforms of integrated sensing and communication (ISAC) are almost based on conventional communication and sensing signal, which bounds both the communication and sensin…
SORIS: A Self-Organized Reconfigurable Intelligent Surface Architecture for Wireless Communications
Evangelos Koutsonas, Alexandros-Apostolos A. Boulogeorgos, Stylianos E. Trevlakis +3
In this paper, a new reconfigurable intelligent surface (RIS) hardware architecture, called self-organized RIS (SORIS), is proposed. The architecture incorporates a microcontroller…
Analysis and Design of a Reconfigurable Metasurface based on Chalcogenide Phase-Change Material for Operation in the Near and Mid Infrared
Alexandros Pitilakis, Alexandros Katsios, Alexandros-Apostolos A. Boulogeorgos
We analyze, design and assess the performance of a reflective reconfigurable metasurface (MS) architecture for optical wireless communications. The device is based on the Ge-Sb-Te…
Markov Chain-based Model of Blockchain Radio Access Networks
Vasileios Kouvakis, Stylianos E. Trevlakis, Alexandros-Apostolos A. Boulogeorgos +3
Security has always been a priority, for researchers, service providers and network operators when it comes to radio access networks (RAN). One wireless access approach that has ca…
