Fluid Antenna Aided Orthogonal Beamspace Construction in Near-Field LoS-MIMO Channels
This paper proposes a novel fluid antenna (FA) assisted orthogonal channel construction scheme for the near-field (NF) line-of-sight (LoS) multiple-input multiple-output (MIMO) system. Specifically, we consider a transmitter (Tx) equipped with a fixed-position uniform planar array (UPA) and a mobile receiver (Rx) equip...
