A Physics-based and Data-driven Approach for Localized Statistical Channel Modeling
Shutao Zhang, Xinzhi Ning, Xi Zheng +3
Localized channel modeling is crucial for offline performance optimization of 5G cellular networks, but the existing channel models are for general scenarios and do not capture loc…
Coordinating Multiple Intelligent Reflecting Surfaces without Channel Information
Fan Xu, Jiawei Yao, Wenhai Lai +4
Conventional beamforming methods for intelligent reflecting surfaces (IRSs) or reconfigurable intelligent surfaces (RISs) typically entail the full channel state information (CSI).…
A Data Quality Assessment Framework for AI-enabled Wireless Communication
Hanning Tang, Liusha Yang, Rui Zhou +5
Using artificial intelligent (AI) to re-design and enhance the current wireless communication system is a promising pathway for the future sixth-generation (6G) wireless network. T…
A Linear Time Algorithm for the Optimal Discrete IRS Beamforming
Shuyi Ren, Kaiming Shen, Xin Li +2
It remains an open problem to find the optimal configuration of phase shifts under the discrete constraint for intelligent reflecting surface (IRS) in polynomial time. The above pr…
When Expressivity Meets Trainability: Fewer than Neurons Can Work
Jiawei Zhang, Yushun Zhang, Mingyi Hong +2
Modern neural networks are often quite wide, causing large memory and computation costs. It is thus of great interest to train a narrower network. However, training narrow neural n…
On the Iteration Complexity of Smoothed Proximal ALM for Nonconvex Optimization Problem with Convex Constraints
Jiawei Zhang, Wenqiang Pu, Zhi-Quan Luo
It is well-known that the lower bound of iteration complexity for solving nonconvex unconstrained optimization problems is , which can be achieved by standard gradient de…
