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…
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…
Over-the-Air Modulation for RIS-assisted Symbiotic Radios: Design, Analysis, and Optimization
Hu Zhou, Ying-Chang Liang, Chau Yuen
In reconfigurable intelligent surface (RIS)-assisted symbiotic radio (SR), an RIS is exploited to assist the primary system and to simultaneously operate as a secondary transmitter…
