SSB-Based Sensing-Assisted Robust Beamforming for High-Mobility UAV Communications in LAWN
Aimin Tang, Shuhan Wang, Yin Xu
High-mobility uncrewed aerial vehicle (UAV) communications in low-altitude wireless networks (LAWN) demand reliable beamforming, while conventional feedback-based schemes suffer fr…
MA-Aided Hierarchical Hybrid Beamforming for Multi-User Wideband Beam Squint Mitigation
Cixiao Zhang, Yin Xu, Xinghao Guo +3
In wideband near-field arrays, frequency-dependent array responses cause wavefronts at different frequencies to deviate from that at the center frequency, producing beam squint and…
Preconditioned Conjugate Gradient for MIMO-AFDM System
Jun Zhu, Yin Xu, Dazhi He +3
Affine frequency division multiplexing (AFDM) is a promising chirp-assisted multicarrier waveform for future high mobility communications. A significant challenge in MIMO-AFDM syst…
Fluid Antenna-Empowered Receive Spatial Modulation
Xinghao Guo, Yin Xu, Dazhi He +6
Fluid antenna (FA), as an emerging antenna technology, fully exploits spatial diversity. This paper integrates FA with the receive spatial modulation (RSM) scheme and proposes a no…
Movable Antenna Aided Full-Duplex ISAC System with Self-Interference Mitigation
Size Peng, Yin Xu, Guanli Yi +3
Movable antenna (MA) has shown significant potential for improving the performance of integrated sensing and communication (ISAC) systems. In this paper, we model an MA-aided ISAC…
Fluid Antenna-Aided Robust Secure Transmission for RSMA-ISAC Systems
Cixiao Zhang, Yin Xu, Size Peng +5
This paper leverages fluid antenna (FA) and rate-splitting multiple access (RSMA) to enhance the physical layer security (PLS) of an integrated sensing and communication (ISAC) sys…
