Secure Communication for Spatially Correlated Massive MIMO with Low-Resolution DACs
Dan Yang, Jindan Xu, Wei Xu +3
In this paper, the performance of a secure massive multiple-input multiple-output (MIMO) system adopting low-resolution digital-to-analog converters (DACs) is analyzed over spatial…
Weighted Spectral Efficiency Optimization for Hybrid Beamforming in Multiuser Massive MIMO-OFDM Systems
Jingbo Du, Wei Xu, Chunming Zhao +1
In this paper, we consider hybrid beamforming designs for multiuser massive multiple-input multiple-output (MIMO)-orthogonal frequency division multiplexing (OFDM) systems. Aiming…
Learning Pugachev's Cobra Maneuver for Tail-sitter UAVs Using Acceleration Model
Wei Xu, Fu Zhang
The Pugachev's cobra maneuver is a dramatic and demanding maneuver requiring the aircraft to fly at extremely high Angle of Attacks (AOA) where stalling occurs. This paper consider…
Secrecy Rate Maximization for Intelligent Reflecting Surface Assisted Multi-Antenna Communications
Hong Shen, Wei Xu, Shulei Gong +2
We investigate transmission optimization for intelligent reflecting surface (IRS) assisted multi-antenna systems from the physical-layer security perspective. The design goal is to…
Rethinking Uplink Hybrid Processing: When is Pure Analog Processing Suggested?
Jingbo Du, Wei Xu, Bin Sheng +1
In this correspondence, we analytically characterize the benefit of digital processing in uplink massive multiple-input multiple-output (MIMO) with sub-connected hybrid architectur…
Hybrid Transceiver Optimization for Multi-Hop Communications
Chengwen Xing, Xin Zhao, Shuai Wang +3
Multi-hop communication with the aid of large-scale antenna arrays will play a vital role in future emergence communication systems. In this paper, we investigate amplify-and-forwa…
