Analytical characterization of RIS-aided terahertz links in the presence of beam misalignment
Evangelos N. Papasotiriou, Sotiris Droulias, Angeliki Alexiou
The terahertz (THz) frequency band has recently attracted considerable attention in wireless communications as potential candidate for providing the necessary high bandwidth for de…
Throughput analysis of RIS-assisted UAV wireless systems under disorientation and misalignment
Alexandros-Apostolos A. Boulogeorgos, Angeliki Alexiou, Marco Di Renzo
Reconfigurable intelligent surface (RIS)-assisted unmanned areal vehicles (UAV) communications have been identified as a key enabler of a number of next-generation applications. Ho…
Artificial Intelligence Empowered Multiple Access for Ultra Reliable and Low Latency THz Wireless Networks
Alexandros-Apostolos A. Boulogeorgos, Edwin Yaqub, Rachana Desai +5
Terahertz (THz) wireless networks are expected to catalyze the beyond fifth generation (B5G) era. However, due to the directional nature and the line-of-sight demand of THz links,…
Reconfigurable Intelligent Surface: MIMO or radiating sheet?
Sotiris Droulias, Angeliki Alexiou
A Reconfigurable Intelligent Surface (RIS) redirects and possibly modifies the properties of incident waves, with the aim to restore non-line-of-sight communication links. Composed…
