Reliable Near-Field Multi-User Positioning Informed by Two-Stage MUSIC
Jiaying Li, Haifeng Wen, Changsheng You +2
Near-field localization is a promising technique for high-resolution multi-user positioning in future wireless systems, but its performance is often degraded by scattering-induced…
Near-field Beam Training under Multi-path Channels: A Hybrid Learning-and-Optimization Approach
Jiapeng Li, Changsheng You, Guoliang Cheng +3
For extremely large-scale arrays (XL-arrays), the discrete Fourier transform (DFT) codebook, conventionally used in the far-field, has recently been employed for near-field beam tr…
Mitigating Mixed-field Interference in Near-field and Far-field Communications: An Antenna Selection Approach
Tianyu Liu, Changsheng You, Chao Zhou +3
In mixed near-field and far-field systems, the nonorthogonality between near-field and far-field channels may cause severe inter-user interference and hence degrade rate performanc…
Hybrid-Field Joint Channel and Visible Region Estimation for RIS-Assisted Communications
Xiaokun Tuo, Ming-Min Zhao, Xiang Wang +2
In reconfigurable intelligent surface (RIS)-assisted millimeter-wave (mmWave) communication systems, the large-scale RIS introduces pronounced geometric effects that lead to the co…
Codebook Design for Limited Feedback in Near-Field XL-MIMO Systems
Liujia Yao, Changsheng You, Zixuan Huang +3
In this paper, we study efficient codebook design for limited feedback in extremely large-scale multiple-input-multiple-output (XL-MIMO) frequency division duplexing (FDD) systems.…
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…
Far-Field vs. Near-Field Propagation Channels: Key Differences and Impact on 6G XL-MIMO Performance Evaluation
Zihang Ding, Jianhua Zhang, Changsheng You +5
Extremely large-scale multiple-input multiple-output (XL-MIMO) is regarded as a promising technology for next-generation communication systems. However, this will expand the near-f…
