Finite-Aperture Fluid Antenna Array Design: Analysis and Algorithm
Zhentian Zhang, Kai-Kit Wong, Hao Jiang +3
Finite-aperture constraints render array design nontrivial and can undermine the effectiveness of classical sparse geometries. This letter provides universal guidance for fluid ant…
Fundamental Limits of Localization with Fluid Antenna Systems: A Fisher Information Analysis
Abdelhamid Salem, Kai-Kit Wong, Hyundong Shin +1
In this letter, we investigate the fundamental limits of localization in fluid antenna systems (FAS) utilizing a Fisher-information-theoretic framework. We develop a unified model…
Codebook-based Port Selection and Combining for CSI-Free Uplink Fluid Antenna Multiple Access
