Scalable Fluid Antenna Systems: A New Paradigm for Array Signal Processing
Tuo Wu, Ye Tian, Jie Tang +8
Most existing antenna array-based source localization methods rely on fixed-position arrays (FPAs) and strict assumptions about source field conditions (near-field or far-field), w…
Sparse Fluid Antenna Arrays: Continuous Position Design Beyond Classical DOF Limits
Tuo Wu, Jie Tang, Ye Tian +3
Fluid antenna system (FAS), which continuously repositions a single physical element across a deployment region , breaks this limit by freeing antenna positions from the di…
Hybrid Architecture Gets Fluid: A New Paradigm for Direction-of-arrival Estimation in 6G Networks
Ye Tian, Jiaji Ren, Tuo Wu +5
High-precision direction-of-arrival (DOA) estimation, as a key sensing capability for 6G-enabled applications such as autonomous driving and extended reality, is increasingly depen…
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…
Beyond : Can Arbitrary EMVS Arrays Achieve Unambiguous NLOS Localization?
Hua Chen, Zhenhao Yu, Tuo Wu +5
Conventional radar array design mandates interelement spacing not exceeding half a wavelength () to avoid spatial ambiguity, fundamentally limiting array aperture and angular…
Reimagining Wireless Connectivity: The FAS-RIS Synergy for 6G Smart Cities
Tuo Wu, Kai-Kit Wong, Jie Tang +6
Fluid antenna system (FAS) represents the concept of treating antenna as a reconfigurable physical-layer resource to broaden system design and network optimization and inspire next…
