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…
Channel Estimation for Holographic MIMO: Wavenumber-Domain Sparsity Inspired Approaches
Yuqing Guo, Yuanbin Chen, Ying Wang
This paper investigates the sparse channel estimation for holographic multiple-input multiple-output (HMIMO) systems. Given that the wavenumber-domain representation is based on a…
Wavenumber Domain Sparse Channel Estimation in Holographic MIMO
Xufeng Guo, Yuanbin Chen, Ying Wang +2
In this paper, we investigate the sparse channel estimation in holographic multiple-input multiple-output (HMIMO) systems. The conventional angular-domain representation fails to c…
Near-Field Sparse Channel Estimation for Extremely Large-Scale RIS-Aided Wireless Communications
Zixing Tang, Yuanbin Chen, Ying Wang +4
A significant increase in the number of reconfigurable intelligent surface (RIS) elements results in a spherical wavefront in the near field of extremely large-scale RIS (XL-RIS).…
