Outage Analysis and Fairness Design for Spatially Correlated FAS-Enabled RSMA Systems
Jinyuan Liu, Yong Liang Guan, Tuo Wu +3
Sixth-generation (6G) systems target higher reliability, denser connectivity, and tighter interference control. {Within this context, rate-splitting multiple access (RSMA) is envis…
Fundamental Analysis of Scalable Fluid Antenna Systems: Identifiability Limits, Information Theory, and Joint Processing
Tuo Wu, Kai-Kit Wong, Jie Tang +8
Unlike fixed-position arrays with static observation entropy, the scalable fluid antenna system (S-FAS) can dynamically adjust its aperture to form different observation spaces wit…
Exact Statistical Characterization and Performance Analysis of Fluid Reconfigurable Intelligent Surfaces
Masoud Khazaee, Felipe A. P. de Figueiredo, Rausley A. A. de Souza +4
Fluid reconfigurable intelligent surfaces (FRIS) extend conventional RIS architectures by enabling physical reconfiguration of element positions, thereby introducing a fundamentall…
Physical Layer Security for FAS-Aided Short-Packet Systems: A Variable Block-Correlation Approach
Jianchao Zheng, Tuo Wu, Kai-Kit Wong +5
This paper presents a comprehensive physical layer security (PLS) framework for fluid antenna system (FAS)-aided short-packet communications under the variable block-correlation mo…
Taming the Bessel Landscape: Joint Antenna Position Optimization for Spatial Decorrelation in Fluid MIMO Systems
Tuo Wu, Kai-Kit Wong, Baiyang Liu +2
When the concept of fluid antenna system (FAS) is applied to multiple-input multiple-output (MIMO) systems, this gives rise to MIMO-FAS, a.k.a.~fluid MIMO. Under rich scattering, t…
Intelligent Sky Mirrors: SAC-Driven MF-RIS Optimization for Secure NOMA in Low-Altitude Economy
Sai Zhao, Fanjin Kong, Dong Tang +5
Low-altitude economy (LAE) has become a key driving force for smart cities and economic growth. To address spectral efficiency and communication security challenges in LAE, this pa…
