This paper investigates sensing parameter estimation for movable antenna (MA) integrated sensing and communication (ISAC) systems under hybrid-field propagation. Specifically, to characterize the coexistence of near-field spherical wavefronts and far-field plane wavefronts, a hybrid-field sensing signal model is first...

Movable antenna (MA) technology has recently emerged as a promising paradigm for enhancing the flexibility and performance of wireless systems by allowing antennas to dynamically adjust their spatial positions within a confined region. Meanwhile, integrated sensing and communication (ISAC) has attracted significant att...

Dynamic environments pose fundamental challenges to integrated sensing and communication (ISAC), particularly due to severe Doppler effects, rapidly time-varying channels, and the intricate coupling between delay and Doppler shifts. Affine frequency-division multiplexing (AFDM), with its inherent capability of characte...
