Robust Beamforming for Multiuser MIMO Systems with Unknown Channel Statistics: A Hybrid Offline-Online Framework
Wenzhuo Zou, Ming-Min Zhao, An Liu +1
Robust beamforming design under imperfect channel state information (CSI) is a fundamental challenge in multiuser multiple-input multiple-output (MU-MIMO) systems, particularly whe…
Cross-Sparsity-Enabled Multipath Perception via Structured Bayesian Inference for Multi-Target Estimation
Xiang Chen, Ming-Min Zhao, An Liu +3
In this paper, we investigate a multi-target sensing system in multipath environment, where inter-target scattering gives rise to first-order reflected paths whose angles of depart…
Near-Field Sparse Bayesian Channel Estimation and Tracking for XL-IRS-Aided Wideband mmWave Systems
Xiaokun Tuo, Zijian Chen, Ming-Min Zhao +2
The rapid development of 6G systems demands advanced technologies to boost network capacity and spectral efficiency, particularly in the context of intelligent reflecting surfaces…
Outage-Aware Sum Rate Maximization in Movable Antennas-Enabled Systems
Guojie Hu, Qingqing Wu, Ming-Min Zhao +4
In this paper, we investigate the movable antennas (MAs)-enabled multiple-input-single-output (MISO) systems, where the base station (BS) equipped with multiple MAs serves multiple…
Efficient Channel Estimation for Rotatable Antenna-Enabled Wireless Communication
Xue Xiong, Beixiong Zheng, Wen Wu +4
Non-fixed flexible antenna architectures, such as fluid antenna system (FAS), movable antenna (MA), and pinching antenna, have garnered significant interest in recent years. Among…
Sensing-Then-Beamforming: Robust Transmission Design for RIS-Empowered Integrated Sensing and Covert Communication
Xingyu Zhao, Min Li, Ming-Min Zhao +2
Traditional covert communication often relies on the knowledge of the warden's channel state information, which is inherently challenging to obtain due to the non-cooperative natur…
