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…
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…
Angular-Distance Based Channel Estimation for Holographic MIMO
Yuanbin Chen, Ying Wang, Zhaocheng Wang +1
This paper investigates the channel estimation for holographic MIMO systems by unmasking their distinctions from the conventional one. Specifically, we elucidate that the channel e…
