Joint Near-Field Target Tracking and Communications with full Duplex Holographic MIMO

Ioannis Gavras, George C. Alexandropoulos

ICASSP 2024accepted

In this paper, we present a simultaneous target tracking and multi-user communications system realized by a full duplex holographic Multiple-Input Multiple-Output (MIMO) node equipped with Dynamic Metasurface Antennas (DMAs) at both its communication ends. Focusing on the near-field regime, we exten…

Near-Field Localization with 1-bit Quantized Hybrid A/D Reception

Ioannis Gavras, Italo Atzeni, George C. Alexandropoulos

ICASSP 2024accepted

In this paper, we consider a hybrid Analog and Digital (A/D) receiver architecture with an extremely large Dynamic Metasurface Antenna (DMA) and an 1-bit resolution Analog-to-Digital Converter (ADC) at each of its reception radio-frequency chains, and present a localization approach for User Equipme…
