Implementing Fluid Antennas in the Beamspace: Performance Evaluation and Codebook Design

David Morales-Jim\'enez, F. Javier L\'opez-Mart\'inez, Pablo Ram\'irez-Espinosa

Claims

C1strongest claim

Importantly, we show that, with proper design, metasurface-based FASs can significantly outperform conceptual ones.

C2weakest assumption

The signal model extension assumes that the metasurface response can be accurately incorporated into the equivalent channel and correlation structure for electronically-reconfigurable designs.

C3one line summary

Metasurface-based fluid antennas outperform conceptual fluid antennas in interference-heavy multi-user scenarios by exploiting projection onto the interference null space.
