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…
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…
Simultaneous Information and Control Signalling Protocol for RIS-Empowered Wireless Systems
Evangelos Koutsonas, Xiaonan Mu, Nan Qi +3
Integration of RIS in radio access networks requires signaling between edge units and the RIS microcontroller (MC). Unfortunately, in several practical scenarios, the signaling lat…
Spiking Neural Networks for Resource Allocation in UAV-Enabled Wireless Networks
Vasileios Kouvakis, Stylianos E. Trevlakis, Ioannis Arapakis +1
This work presents a new spiking neural network (SNN)-based approach for user equipment-base station (UE-BS) association in non-terrestrial networks (NTNs). With the introduction o…
Modeling blockage in high directional wireless. systems
Evangelos Koutsonas, Alexandros-Apostolos A. Boulogeorgos, Stylianos E. Trevlakis +2
While the wireless word moves towards higher frequency bands, new challenges arises, due to the inherent characteristics of the transmission links, such as high path and penetratio…
Can graph neural network-based detection mitigate the impact of hardware imperfections?
Lamprini Mitsiou, Stylianos Trevlakis, Argiris Tsiolas +3
Until recently, researchers used machine learning methods to compensate for hardware imperfections at the symbol level, indicating that optimum radio-frequency transceiver performa…
