Revisiting XL-MIMO Channel Estimation: When Dual-Wideband Effects Meet Near Field
Anzheng Tang, Jun-Bo Wang, Yijin Pan +4
The deployment of extremely large antenna arrays (ELAAs) in extremely large-scale multiple-input multiple-output (XL-MIMO) systems introduces significant near-field effects, such a…
Revealing the evanescent components in Kronecker-product based codebooks: insights and implications
Jun Yang, Yijian Chen, Yunqi Sun +4
The orthogonal bases of discrete Fourier transform (DFT) has been recognized as the standard spatial-domain bases for Type I, Type II and enhanced Type II codewords by the 3rd Gene…
Channel Estimation for XL-MIMO Systems with Decentralized Baseband Processing: Integrating Local Reconstruction with Global Refinement
Anzheng Tang, Jun-Bo Wang, Yijin Pan +6
In this paper, we investigate the channel estimation problem for extremely large-scale multiple-input multiple-output (XL-MIMO) systems with a hybrid analog-digital architecture, i…
Spatial Bandwidth of Bilateral Near-Field Channels for Linear Large-Scale Antenna Array System
Zhen Wang, Yijin Pan, Jun-Bo Wang +2
This paper analyzes the spatial bandwidth of line-of-sight (LoS) channels in massive MIMO systems. For the linear large-scale antenna arrays (LSAA) of transceivers placed in random…
