Spatial Semantic Communication: When Semantic Transmission Meets Index Modulation
Xinghao Guo, Yin Xu, Dazhi He +5
Current digital semantic communication systems have primarily focused on maintaining compatibility with conventional constellation-based modulation. In contrast, index modulation (…
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…
A Contemporary Survey on Fluid Antenna Systems: Fundamentals and Networking Perspectives
Hanjiang Hong, Kai-Kit Wong, Hao Xu +8
The explosive growth of teletraffic, fueled by the convergence of cyber-physical systems and data-intensive applications, such as the Internet of Things (IoT), autonomous systems,…
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…
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…
Fluid Antenna Index Modulation for MIMO Systems: Robust Transmission and Low-Complexity Detection
Xinghao Guo, Yin Xu, Dazhi He +5
The fluid antenna (FA) index modulation (IM)-enabled multiple-input multiple-output (MIMO) system, referred to as FA-IM, significantly enhances spectral efficiency (SE) compared to…
