Hybrid Beamforming Design for Covert mmWave MIMO with Finite-Resolution DACs
Wei Ci, Chenhao Qi, Xiaohu You
We investigate hybrid beamforming design for covert millimeter wave multiple-input multiple-output systems with finite-resolution digital-to-analog converters (DACs), which impose…
Spatially Correlated RIS-Aided Secure Massive MIMO Under CSI and Hardware Imperfections
Dan Yang, Jindan Xu, Wei Xu +4
This paper investigates the integration of a reconfigurable intelligent surface (RIS) into a secure multiuser massive multiple-input multiple-output (MIMO) system in the presence o…
Secure Outage Analysis for RIS-Aided MISO Systems with Randomly Located Eavesdroppers
Wei Shi, Jindan Xu, Wei Xu +4
In this paper, we consider the physical layer security of an RIS-assisted multiple-antenna communication system with randomly located eavesdroppers. The exact distributions of the…
Low-Complexity Channel Estimation for Extremely Large-Scale MIMO in Near Field
Chun Huang, Jindan Xu, Wei Xu +3
The extremely large-scale massive multiple-input multiple-output (XL-MIMO) has the potential to achieve boosted spectral efficiency and refined spatial resolution for future wirele…
