Joint Beamforming Design and Port Selection in Fluid Antenna-Assisted Multi-Cell Networks: A Personalized Federated Learning Approach

This paper investigates joint beamforming and port selection in multi-cell fluid antenna-assisted (FAS) networks. In such networks, active beamforming and discrete FA port selection are coupled through intra-cell and inter-cell interference and are jointly optimized to maximize the weighted sum-rate (WSR). We develop a...

Near-Field Dual-UPA Communications: A Generalized Geometric Approach

A generalized geometric model is developed to calculate the 3D distance between arbitrary antenna elements across the transmitter and receiver panels and derives a closed-form near-field to far-field (NF-FF) boundary for dual-UPA configurations.
