Communication-Efficient Multi-Modal Edge Inference via Uncertainty-Aware Distributed Learning
Hang Zhao, Hongru Li, Dongfang Xu +2
Semantic communication is emerging as a key enabler for distributed edge intelligence due to its capability to convey task-relevant meaning. However, achieving communication-effici…
Adaptive Sensing Performance Design for Enhancing Secure Communication in Networked ISAC Systems
Yiming Xu, Dongfang Xu, Shenghui Song +1
The channel state information (CSI) of an eavesdropper is crucial for physical layer security (PLS) design, but it is difficult to obtain due to the passive and non-cooperative nat…
Fluid Antenna Meets RIS: Random Matrix Analysis and Two-Timescale Design for Multi-User Communications
Xin Zhang, Dongfang Xu, Jingjing Wang +3
The reconfigurability of fluid antenna systems (FASs) and reconfigurable intelligent surfaces (RISs) provides significant flexibility in optimizing channel conditions by jointly ad…
No Eigenvalues Outside the Limiting Support of Generally Correlated and Noncentral Sample Covariance Matrices
Zeyan Zhuang, Xin Zhang, Dongfang Xu +1
Spectral properties of random matrices play an important role in statistics, machine learning, communications, and many other areas. Engaging results regarding the convergence of t…
Joint Radiation Power, Antenna Position, and Beamforming Optimization for Pinching-Antenna Systems with Motion Power Consumption
Yiming Xu, Dongfang Xu, Xianghao Yu +3
Pinching-antenna systems (PASS) have been recently proposed to improve the performance of wireless networks by reconfiguring both the large-scale and small-scale channel conditions…
Decentralized MIMO Systems with Imperfect CSI using LMMSE Receivers
Zeyan Zhuang, Xin Zhang, Dongfang Xu +2
Centralized baseband processing (CBP) is required to achieve the full potential of massive multiple-input multiple-output (MIMO) systems. However, due to the large number of antenn…
