Modeling and Performance Evaluation of Distributed Satellite Antennas: Space Is Much Closer Than One Might Think
Giacomo Bacci, Riccardo De Gaudenzi, Marco Luise +1
Distributed satellites can deliver broadband connectivity directly to commercial handsets. In the formation of arrays (FoA) architecture, cooperating satellites synthesize a large…
On the Unilateral Approximation Condition with Linear Arrays in Near-Field NLoS Propagation
Aniol Martí, Luca Sanguinetti, Xavier Gràcia
This paper investigates the validity of the unilateral approximation in near-field non-line-of-sight (NLoS) propagation for large-scale linear antenna arrays. Utilizing multiport c…
A Novel Near-Field Dictionary Design for Hybrid MIMO with Uniform Planar Arrays
Luca Antonelli, Antonio Alberto D Amico, Luca Sanguinetti
Near-field ultra-massive MIMO (U-MIMO) systems provide enhanced spatial resolution but present challenges for channel estimation, particularly when hybrid architectures are employe…
Near-Field MMSE Channel Estimation for THz RIS-aided Communications with Electromagnetic Interference
Wen-Xuan Long, Marco Moretti, Giacomo Bacci +1
This letter investigates the channel estimation problem in THz wireless communications where a RIS is employed to assist wireless transmission between different devices. Unlike exi…
Goal-Oriented Access Optimization for ISAC-Enabled Digital Twins
Fabio Saggese, Federico Chiariotti, Shashi Raj Pandey +3
Digital twins (DTs) of physical systems enable real-time remote tracking, control, and learning, but require to be updated with environmental sensory data to maintain alignment wit…
An Enhanced Polar-Domain Dictionary Design for Elevated BSs in Near-Field U-MIMO
Luca Antonelli, Antonio Alberto D'Amico, Luca Sanguinetti
Near-field U-MIMO communications require carefully optimized sampling grids in both angular and distance domains. However, most existing grid design methods neglect the influence o…
