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 (…
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…
Downlink OFDM-FAMA in 5G-NR Systems
Hanjiang Hong, Kai-Kit Wong, Hao Xu +5
Fluid antenna multiple access (FAMA), enabled by the fluid antenna system (FAS), offers a new and straightforward solution to massive connectivity. Previous results on FAMA were pr…
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…
