Joint EM-BB Beamforming Design for ISAC Systems With Reconfigurable Antenna Arrays

This paper investigates the joint electromagnetic (EM)-domain and baseband (BB)-domain beamforming for integrated sensing and communication (ISAC) systems enabled by pattern- and polarization-reconfigurable pixel-antenna arrays. A multiport-network-based antenna model is developed to map each binary switch configuratio...

Delay-Doppler Sensing Performance Analysis for MIMO-OFDM ISAC Systems

This paper analyzes a multi-input multi-output (MIMO)-OFDM-ISAC system in which multiple data streams jointly illuminate a sensing target, and derives second-order moment expressions for the RDM under matched filtering (MF) and reciprocal filtering (RF), and uses them to characterize the dynamic range (DR).
