CSI Reconstruction in Fluid Antenna Systems Without Spatial Covariance Priors

Fluid antenna systems (FASs) exploit many candidate ports for spatial diversity, but hardware constraints allow channel observations at only a few active ports. Whether full-port CSI can be recovered without pre-acquired channel statistics remains open. Under the Clarke isotropic scattering model, we show that the chan...

Block-Correlation-Based Outage Analysis for FAS-Assisted Wireless Powered Communication

A fluid antenna system (FAS) can improve both energy harvesting and data transmission in wireless powered communication (WPC) by exploiting spatial diversity with a single RF chain. In this letter, we study the outage probability of a FAS-assisted WPC network under the port selection criterion that maximizes the produc...

Unlocking Downlink NOMA with FARIS: Joint Clustering and Surface Configuration Design

A network sum-rate maximization problem that jointly optimizes user clustering, NOMA power allocation, FARIS amplification gains, discrete phase shifts, and fluid element selection under quality-of-service, reflected-power, and hardware constraints is formulated.
