From Sparse Probes to Sum-Rate Maximization: Electromagnetic Twin Beamforming
Tuo Wu, Kangda Zhi, Jie Tang +3
Probing every candidate location at each wireless-map update is costly. This letter develops electromagnetic-twin (ET) beamforming that converts sparse spatial probes into a sum-ra…
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…
FAS-RIS for V2X: Unlocking Realistic Performance Analysis with Finite Elements
Tuo Wu, Xiazhi Lai, Maged Elkashlan +3
The synergy of fluid antenna systems (FAS) and reconfigurable intelligent surfaces (RIS) is poised to unlock robust Vehicle-to-Everything (V2X) communications. However, a critical…
Variable Block-Correlation Modeling and Optimization for Secrecy Analysis in Fluid Antenna Systems
Tuo Wu, Kwai-Man Luk, Jie Tang +9
Fluid antenna systems (FAS) are emerging as a transformative enabler for sixth-generation (6G) wireless communications, providing unprecedented spatial diversity through dynamic re…
Rethinking Hardware Impairments in Multi-User Systems: Can FAS Make a Difference?
Junteng Yao, Tuo Wu, Liaoshi Zhou +7
In this paper, we analyze the role of fluid antenna systems (FAS) in multi-user systems with hardware impairments (HIs). Specifically, we investigate a scenario where a base statio…
A Secure Beamforming Design: When Fluid Antenna Meets NOMA
Lifeng Mai, Junteng Yao, Jie Tang +4
This letter proposes a secure beamforming design for downlink non-orthogonal multiple access (NOMA) systems utilizing fluid antenna systems (FAS). We consider a setup where a base…
