Scintillation and Attenuation Modelling of Atmospheric Turbulence for Terahertz UAV Channels
Weijun Gao, Chong Han, Zhi Chen
Terahertz (THz) wireless communications have the potential to realize ultra-high-speed and secure data transfer with miniaturized devices for unmanned aerial vehicle (UAV) communic…
Cooperative Beamforming for RIS-Aided Cell-Free Massive MIMO Networks
Xinying Ma, Deyou Zhang, Ming Xiao +2
The combination of cell-free massive multiple-input multiple-output (CF-mMIMO) and reconfigurable intelligent surface (RIS) is envisioned as a promising paradigm to improve network…
Nanoscale Reconfigurable Intelligent Surface Design and Performance Analysis for Terahertz Communications
Xinying Ma, Zhi Chen, Chongwen Huang
Terahertz (THz) communications have been envisioned as a promising enabler to provide ultra-high data transmission for sixth generation (6G) wireless networks. To tackle the blocka…
MIMO Secret Communications Against an Active Eavesdropper
Lingxiang Li, Athina P. Petropulu, Zhi Chen
This paper considers a scenario in which an Alice-Bob pair wishes to communicate in secret in the presence of an active Eve, who is capable of jamming as well as eavesdropping in F…
GSVD-Based Precoding in MIMO Systems With Integrated Services
Weidong Mei, Zhi Chen, Jun Fang
This letter considers a two-receiver multiple-input multiple-output (MIMO) Gaussian broadcast channel model with integrated services. Specifically, we combine two sorts of service…
Linear Precoder Design for a MIMO Gaussian Wiretap Channel with Full-Duplex Source and Destination Nodes
Lingxiang Li, Zhi Chen, A. P. Petropulu +1
We consider linear precoder design for a multiple-input multiple-output (MIMO) Gaussian wiretap channel, which comprises two legitimate nodes, i.e., Alice and Bob, operating in Ful…
