Joint Channel Estimation and Sensing for Wideband mmWave Systems With Beam Squint and Split

Next-generation wireless communications must be capable of meeting large capacity demands while simultaneously enabling highly accurate sensing. Millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) is a pivotal enabler for integrated sensing and communication (ISAC) systems, owing to its large availab...

Joint Discrete Pinching-Antenna Activation and Beamforming Design for Efficient PASS-ISAC

Pinching-antenna systems (PASS) offer flexible radiation points for integrated sensing and communication (ISAC), but existing designs largely assume continuous antenna placement, which may be impractical with pre-installed hardware. We investigate a discrete-activation multi-waveguide PASS-ISAC system that selects spar...

Finite-Blocklength Analysis of RSMA-Aided Fluid Antenna Systems

This letter investigates a fluid antenna system (FAS)-assisted downlink rate-splitting multiple access (RSMA) scheme in the finite blocklength regime. A single traditional antenna system (TAS) base station serves FAS-equipped central and cell-edge users, each with $N$ reconfigurable ports. Spatial correlation among por...
