Robust High-Dimensional MVDR Beamforming under Heavy-Tailed Noise via Spiked Covariance Modeling
Liusha Yang, Shuqi Chai, Manyou Ma
This paper proposes a robust high-dimensional minimum variance distortionless response (MVDR) beamforming method for array observations corrupted by heavy-tailed noise. The propose…
Bounded Deep Unfolding for Joint Beamforming and Scheduling in Multi-Cell MIMO Networks
Jiansheng Li, Shuqi Chai, Fan Xu +4
This paper investigates the joint resource block group (RBG) scheduling and beamforming optimization problem for weighted sum-rate (WSR) maximization in multi-cell multiuser multip…
Credibility-Aware Learning and Control for Safe USV Navigation under Perception Uncertainty
Yuhang Zhang, Shuqi Chai, Yukang Zhang +5
Safe navigation for Unmanned Surface Vehicles (USVs) under the International Regulations for Preventing Collisions at Sea (COLREGs) remains challenging in dynamic maritime environm…
DK-Root: A Joint Data-and-Knowledge-Driven Framework for Root Cause Analysis of QoE Degradations in Mobile Networks
Qizhe Li, Haolong Chen, Jiansheng Li +7
Diagnosing the root causes of Quality of Experience (QoE) degradations in operational mobile networks is challenging due to complex cross-layer interactions among kernel performanc…
Decentralized Handover Parameter Optimization with MARL for Load Balancing in 5G Networks
Yang Shen, Shuqi Chai, Bing Li +3
In cellular networks, cell handover refers to the process where a device switches from one base station to another, and this mechanism is crucial for balancing the load among diffe…
