Site Geometry and Calibration Uncertainties in Digital Twin-enabled Channel Estimation
Lorenzo Del Moro, Francesco Linsalata, Umberto Spagnolini +1
Fast ray tracing (RT) has stimulated the Digital Twin (DT) as an emerging technology for environment-aware communications. Since wireless propagation is governed by the interaction…
Mobile Radio Networks and Weather Radars Dualism: Rainfall Measurement Revolution in Densely Populated Areas
Davide Tornielli Bellini, Mario Montopoli, Dario Tagliaferri +5
This study demonstrates, for the first time, how a network of cellular base stations (BSs) - the infrastructure of mobile radio networks - can be used as a distributed opportunisti…
Indoor 60 GHz Radio Channel Dataset Enabling Digital Twin Construction
Davide Scazzoli, Daniele de Santis, Francesco Linsalata +3
The ambitious performance targets of modern wireless networks, including 6G and Industrial IoT (IIoT) systems, necessitate advanced hardware platforms utilizing millimeter-wave (mm…
Echo-Side Integrated Sensing and Communication via Space-Time Reconfigurable Intelligent Surfaces
Marouan Mizmizi, Stefano Tebaldini, Umberto Spagnolini
This paper presents an echo-side modulation framework for integrated sensing and communication (ISAC) systems. A space-time reconfigurable intelligent surface (ST-RIS) impresses a…
Enabling NLOS Imaging Capabilities at the Initial Access of 6G Base Stations
Davide Tornielli Bellini, Dario Tagliaferri, Pietro Grassi +3
Sensing in non-line-of-sight (NLOS) is one of the major challenges for integrated sensing and communication systems. Existing countermeasures for NLOS either use prior knowledge on…
Towards Channel Charting Enhancement with Non-Reconfigurable Intelligent Surfaces
Mahdi Maleki, Reza Agahzadeh Ayoubi, Marouan Mizmizi +1
We investigate how fully-passive electromagnetic skins (EMSs) can be engineered to enhance channel charting (CC) in dense urban environments. We employ two complementary state-of-t…
