Experimental Study of Interference Suppression for Backscatter Communication in Distributed MIMO
Ahmet Kaplan, Gilles Callebaut, Jarne Van Mulders +1
Bistatic backscatter communication requires strong illumination of a backscatter device (BD), while a spatially separated reader detects the weak modulated reflection. In practice,…
Reciprocity Calibration of Dual-Antenna Repeaters via MMSE Estimation
Shoma Hara, Takumi Takahashi, Hiroki Iimori +2
This paper proposes a novel Bayesian reciprocity calibration method that consistently ensures uplink and downlink channel reciprocity in repeater-assisted multiple-input multiple-o…
Hybrid Channel Estimation with Quantized Phase Feedback for Over-the-Air Computation
Martin Dahl, Erik G. Larsson
To reduce the signaling overhead of over-the-air computation, a hybrid channel estimation scheme is proposed, where reciprocity-based and feedback-based channel estimation are comb…
Drone Surveillance via Coordinated Beam Sweeping in MIMO-ISAC Networks
Palatip Jopanya, Diana P. M. Osorio, Erik G. Larsson
This paper introduces a scheme for drone surveillance coordinated with the fifth generation (5G) synchronization signal block (SSB) cell-search procedure to simultaneously detect l…
Joint Access Point Selection and Beamforming Design for Bistatic Backscatter Communication
Ahmet Kaplan, Diana P. M. Osorio, Erik G. Larsson
Future Internet-of-Things networks are envisioned to use small and cheap sensor nodes with extremely low power consumption to avoid the extensive use of batteries. To provide conne…
Analysis of Broad Beam Beamforming for Collocated and Distributed MIMO
Ahmet Kaplan, Diana P. M. Osorio, Erik G. Larsson
Broad beam beamforming (BF) design in multiple-input multiple-output (MIMO) can be convenient for initial access, synchronization, and sensing capabilities in cellular networks by…
Impact of Network-Controlled Repeaters in Integrated Sensing and Communication Systems
Henrik Åkesson, Diana P. M. Osorio, Erik G. Larsson
Integrating sensing capabilities into existing massive MIMO communication networks has become crucial, stemming from a need for a more interconnected society. Improved coverage and…
Physically Large Apertures for Wireless Power Transfer: Performance and Regulatory Aspects
Benjamin J. B. Deutschmann, Ulrich Muehlmann, Ahmet Kaplan +7
Wireless power transfer (WPT) is a promising service for the Internet of Things, providing a cost-effective and sustainable solution to deploy so-called energy-neutral devices on a…
