Near-Field Beampointing with Low Exposure Regions: a Dominant Subspace Projection Approach
Laurence Defraigne, Gilles Monnoyer, Jérôme Louveaux +1
The spherical nature of the wavefronts exhibited in the near-field of antenna arrays enables advanced beamforming capabilities, such as beampointing and beamnulling. In this paper,…
Resolution-Aliasing Trade-off in Near-Field Localisation
Baptiste Sambon, Gilles Monnoyer, Luc Vandendorpe +1
Extremely Large-scale MIMO (XL-MIMO) systems operating in Near-Field (NF) introduce new degrees of freedom for accurate source localisation, but make dense arrays impractical. Spar…
