Bending beams for 6G near-field communications
Sotiris Droulias, Giorgos Stratidakis, Angeliki Alexiou
Future wireless connectivity is envisioned to accommodate functionalities far beyond broadband data transmission over point-to-point direct links, enabling novel scenarios, such as…
Hierarchical Localization for Integrated Sensing and Communication
Giorgos Stratidakis, Sotiris Droulias, Angeliki Alexiou
Localization is expected to play a significant role in future wireless networks as positioning and situational awareness, navigation and tracking, are integral parts of 6G usage sc…
Reconfigurable Intelligent Surfaces as Spatial Filters
Sotiris Droulias, Giorgos Stratidakis, Emil Björnson +1
The design of Reconfigurable Intelligent Surfaces (RISs) is typically based on treating the RIS as an infinitely large surface that steers incident plane waves toward the desired d…
Near-field orthogonality and cosine beams for near-field space division multiple access in 6G communications and beyond
Sotiris Droulias, Giorgos Stratidakis, Angeliki Alexiou
Spatial division multiple access (SDMA), a powerful method routinely applied in multi-user multiple-input multiple-output (MIMO) communications, relies on the angular orthogonality…
Performance Analysis of Multi-Reconfigurable Intelligent Surface-Empowered THz Wireless Systems
