Multi-RIS-Empowered Multiple Access: A Distributed Sum-Rate Maximization Approach
Konstantinos D. Katsanos, Paolo Di Lorenzo, George C. Alexandropoulos
The plethora of wirelessly connected devices, whose deployment density is expected to largely increase in the upcoming sixth Generation (6G) of wireless networks, will naturally ne…
Power Minimizing MEC Offloading with QoS Constraints over RIS-Empowered Communications
Mattia Merluzzi, Francesca Costanzo, Konstantinos D. Katsanos +2
This work lies at the intersection of two cutting edge technologies envisioned to proliferate in future 6G wireless systems: Multi-access Edge Computing (MEC) and Reconfigurable In…
RIS-Enabled Smart Wireless Environments: Deployment Scenarios, Network Architecture, Bandwidth and Area of Influence
George C. Alexandropoulos, Dinh-Thuy Phan-Huy, Kostantinos D. Katsanos +19
Reconfigurable Intelligent Surfaces (RISs) constitute the key enabler for programmable electromagnetic propagation environments, and are lately being considered as a candidate phys…
Distributed Sum-Rate Maximization of Cellular Communications with Multiple Reconfigurable Intelligent Surfaces
Konstantinos D. Katsanos, Paolo Di Lorenzo, George C. Alexandropoulos
The technology of Reconfigurable Intelligent Surfaces (RISs) has lately attracted considerable interest from both academia and industry as a low-cost solution for coverage extensio…
Uncertainty Principle and Sampling of Signals Defined on Graphs
Mikhail Tsitsvero, Sergio Barbarossa, Paolo Di Lorenzo
In many applications, from sensor to social networks, gene regulatory networks or big data, observations can be represented as a signal defined over the vertices of a graph. Buildi…
