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…
