Holographic MIMO Communications: What is the benefit of closely spaced antennas?
Antonio Alberto D'Amico, Luca Sanguinetti
Holographic MIMO refers to a (possibly large) array with a large number of individually controlled and densely deployed antennas. The objective of this paper is to provide further…
DFT-Based Channel Estimation for Holographic MIMO
Antonio Alberto D'Amico, Giacomo Bacci, Luca Sanguinetti
Holographic MIMO (hMIMO) systems with a massive number of individually controlled antennas N make minimum mean square error (MMSE) channel estimation particularly challenging, due…
Performance analysis of WDM in LoS communications with arbitrary orientation and position
Antonio Alberto D'Amico, Luca Sanguinetti, Merouane Debbah
This letter considers the wavenumber-division-multiplexing (WDM) scheme that was recently proposed in [1] for line-of-sight communications between parallel (side-by-side) spatially…
Cramér-Rao Bounds for Holographic Positioning
Antonio A. D'Amico, Andrea de Jesus Torres, Luca Sanguinetti +1
Multiple antennas arrays play a key role in wireless networks for communications but also for localization and sensing applications. The use of large antenna arrays at high carrier…
Wavenumber-Division Multiplexing in Line-of-Sight Holographic MIMO Communications
Luca Sanguinetti, Antonio A. D'Amico, Merouane Debbah
Starting from first principles of wave propagation, we consider a multiple-input multiple-output (MIMO) representation of a communication system between two spatially-continuous vo…
Cramér-Rao Bounds for Near-Field Localization
Andrea De Jesus Torres, Antonio Alberto D'Amico, Luca Sanguinetti +1
Multiple antenna arrays play a key role in wireless networks for communications but also localization and sensing. The use of large antenna arrays pushes towards a propagation regi…
Random Access in Massive MIMO by Exploiting Timing Offsets and Excess Antennas
