Learning or Modeling? Virtual XL-RIS Observation Reconstruction for Near-Field Sensing
Tuo Wu, Jie Tang, Jiacheng Wang +5
A passive extremely large-scale reconfigurable intelligent surface (XL-RIS) offers a position-sensitive aperture for near-field sensing, but its element-wise signals are not direct…
Sparse Channel Acquisition in Aging Fluid Antenna Systems: A Reliability-Calibrated Posterior Reconstruction Approach
Xiaokai Song, Jie Tang, Tuo Wu +5
Fluid antenna systems (FASs) exploit port-domain diversity within a compact aperture, but their gain can be lost if the receiver has to scan too many ports before data transmission…
Reconfiguring Sparse Apertures: Partial-Mobility Planar FAS for 2-D DOA Estimation
Xiaokai Song, Tuo Wu, Jie Tang +3
Classical sparse arrays enlarge the sensing aperture under limited element and radio-frequency (RF) chain budgets, but their fixed geometries impose a persistent tradeoff between w…
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…
Electromagnetic Twin: Completing the Wireless World from Sparse Channel Evidence
Tuo Wu, Jie Tang, Kangda Zhi +5
Acquiring dense channel information over many locations and beams incurs considerable pilot and processing overhead. Radio maps and channel knowledge maps (CKMs) reduce this overhe…
How Many Independent Modes Does a Fluid Antenna Have? A Closed-Form Outage Analysis via Equivalent Degrees of Freedom
Tuo Wu, Junteng Yao, Kai-Kit Wong +5
In a fluid antenna system (FAS), a single reconfigurable antenna is able to activate one of correlated ports to exploit spatial diversity. However, outage analysis is challengi…
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…
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…
Rotatable Antenna Enhanced Multicast Communication System
Weihua Zhu, Beixiong Zheng, Lipeng Zhu +2
Rotatable antenna (RA) provides additional spatial degrees of freedom (DoFs) for communication systems by enabling per-antenna dynamic boresight adjustment, which is attractive for…
Rotatable Antenna-Enabled Mobile Edge Computing
Qiyao Wang, Beixiong Zheng, Xue Xiong +4
In the evolving landscape of mobile edge computing (MEC), enhancing communication reliability and computation efficiency to support increasingly stringent low-latency services rema…
