On the Performance of THz Wireless Systems over - Channels with Beam Misalignment, Mobility and Hardware Impairments
Wamberto J. L. Queiroz, Higo T. P. Silva, Hugerles S. Silva +1
This paper investigates the performance of terahertz (THz) wireless systems over the - fading channels with beam misalignment, mobility and hardware impairments. Ne…
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…
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…
Coalition Formation for Heterogeneous Federated Learning Enabled Channel Estimation in RIS-assisted Cell-free MIMO
Nan Qi, Haoxuan Liu, Theodoros A. Tsiftsis +4
Downlink channel estimation remains a significant bottleneck in reconfigurable intelligent surface-assisted cell-free multiple-input multiple-output communication systems. Conventi…
High-Fidelity Coherent-One-Way QKD Simulation Framework for 6G Networks: Bridging Theory and Reality
Aitor Brazaola-Vicario, Vasileios Kouvakis, Stylianos E. Trevlakis +4
Quantum key distribution (QKD) has been emerged as a promising solution for guaranteeing information-theoretic security. Inspired by this, a great amount of research effort has bee…
