Wideband Physical Layer Security in Mixed Near-Field and Far-Field Communications
Yunpu Zhang, Changsheng You, Hing Cheung So
Prior studies on wideband physical layer security (PLS) have mostly focused on either far-field or near-field communication systems. In this paper, we investigate PLS in a more gen…
Electromagnetic Twin: From Sparse Measurements to Persistent Wireless Intelligence
Tuo Wu, Lifeng Mai, Jie Tang +7
Radio maps and channel knowledge maps provide reusable propagation knowledge, but a stored map can become locally outdated after persistent changes to doors, partitions, furniture,…
Positioning with Flexible Reflectors: Solution and Performance Analysis
Jiajun He, Han Yu, Danyan Lin +4
Flexible reflectors (FRs) have emerged as a low-cost and energy-efficient solution for reshaping electromagnetic propagation environments across a wide range of applications. This…
Enhanced Byzantine-Robust Federated Learning Via Truncated-Quadratic Loss for Heterogeneous Data
Zhi-Yong Wang, Hao Nan Sheng, Werner Stefan +3
Federated learning distributes data among clients, making it vulnerable to malicious attacks and data heterogeneity, which together pose challenges for robust learning. To tack…
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…
Rotatable Antenna Enabled Multi-Cell Mixed Near-Field and Far-Field Communications
Yunpu Zhang, Changsheng You, Ruichen Zhang +4
Prior studies on mixed near-field and far-field communications have focused exclusively on single-cell scenarios, where both near-field and far-field users are served by the same b…
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…
Merging Beyond: Streaming LLM Updates via Activation-Guided Rotations
Yuxuan Yao, Haonan Sheng, Qingsong Lv +11
The escalating scale of Large Language Models (LLMs) necessitates efficient adaptation techniques. Model merging has gained prominence for its efficiency and controllability. Howev…
