Abstract
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 extend
Fresnel's approximation to metasurfaces and devise a subspace tracking scheme
with DMA-based hybrid Analog and Digital (A/D) reception as well as hybrid A/D
transmission with a DMA for sum-rate maximization. The presented simulation
results corroborate the efficiency of the proposed framework for various system
parameters.
