Two-timescale Beamforming Optimization for Downlink Multi-user Holographic MIMO Surfaces
Haochen Wu, Yuanbin Chen, Yang Ming +1
Benefiting from the rapid development of metamaterials and metasurfaces, the holographic multiple-input and multiple-output surface (HMIMOS) has been regarded as a promising soluti…
New Paradigm for Unified Near-Field and Far-Field Wireless Communications
Zhaocheng Wang, Haochen Wu, Yuanbin Chen +1
Current Type I and Type II codebooks in fifth generation (5G) wireless communications are limited in supporting the coexistence of far-field and near-field user equipments, as they…
MIMO Precoding Exploiting Extra Degrees of Freedom (DoF) in the Wavenumber Domain
Yuanbin Chen, Xufeng Guo, Tianqi Mao +3
In this paper, we propose an emerging wavenumber-domain precoding scheme to break the limitations of rank-1 channels that merely supports single-stream transmission, enabling simul…
Wavenumber-Domain Near-Field Channel Estimation: Beyond the Fresnel Bound
Xufeng Guo, Yuanbin Chen, Ying Wang +2
In the near-field context, the Fresnel approximation is typically employed to mathematically represent solvable functions of spherical waves. However, these efforts may fail to tak…
Unified Far-Field and Near-Field in Holographic MIMO: A Wavenumber-Domain Perspective
Yuanbin Chen, Xufeng Guo, Gui Zhou +3
This article conceives a unified representation for near-field and far-field holographic multiple-input multiple-output (HMIMO) channels, addressing a practical design dilemma: "Wh…
Exploiting Structured Sparsity in Near Field: From the Perspective of Decomposition
Xufeng Guo, Yuanbin Chen, Ying Wang +1
The structured sparsity can be leveraged in traditional far-field channels, greatly facilitating efficient sparse channel recovery by compressing the complexity of overheads to the…
