Near-Field Communications with Different Array Geometries: Rayleigh Distance, Channel Estimation, and Transmission Design
Kangda Zhi, Yi Song, Tianyu Yang +5
This work establishes a framework of near-field communication under different array geometries of extremely large-scale multiple-input multiple-output (XL-MIMO). We first formulate…
Near-Field 3D Localization and MIMO Channel Estimation with Sub-Connected Planar Arrays
Kangda Zhi, Tianyu Yang, Songyan Xue +1
This paper investigates the design of channel estimation and 3D localization algorithms in a challenging scenario, where a sub-connected planar extremely large-scale multiple-input…
Near-Field Integrated Imaging and Communication in Distributed MIMO Networks
Kangda Zhi, Tianyu Yang, Shuangyang Li +3
In this work, we propose a general framework for wireless imaging in distributed MIMO wideband communication systems, considering multi-view non-isotropic targets and near-field pr…
Holographic MIMO Multi-Cell Communications
Kangda Zhi, Tianyu Yang, Shuangyang Li +3
Metamaterial antennas are appealing for next-generation wireless networks due to their simplified hardware and much-reduced size, power, and cost. This paper investigates the holog…
