NeuroRIS: Neuromorphic-Inspired Metasurfaces
Christos G. Tsinos, Alexandros-Apostolos A. Boulogeorgos, Theodoros A. Tsiftsis
Reconfigurable intelligent surfaces (RISs) operate similarly to electromagnetic (EM) mirrors and remarkably go beyond Snell law to generate an applicable EM environment allowing fo…
Holographic RIS Empowered THz Communications with Hardware Imperfections under Adverse Weather Conditions
Alexandros-Apostolos A. Boulogeorgos, Stylianos Trevlakis, Theodoros A. Tsiftsis
This paper focuses on providing a theoretical framework for the evaluation of the performance of holographic reconfigurable intelligent surface (HRIS) empowered terahertz (THz) wir…
Training Terahertz Wireless Systems to Battle I/Q Imbalance
Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou
Due to the non-ideality of analog components, transceivers experience high levels of hardware imperfections, like in-phase and quadrature imbalance (IQI), which manifests itself as…
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…
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…
On the Ergodic Secrecy Capacity of Reconfigurable Intelligent Surface Aided Wireless Systems Under Mixture Gamma Fading
Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou
This paper presents a quantified assessment of the physical layer security capabilities of reconfigurable intelligent surface (RIS)-aided wireless systems under eavesdropping. Spec…
