On Secure NOMA-CDRT Systems with Physical Layer Network Coding
Hongjiang Lei, Xusheng She, Ki-Hong Park +4
This paper proposes a new scheme to enhance the secrecy performance of a NOMA-based coordinated direct relay transmission system (NOMA-CDRT) with an untrusted relay. The physical-l…
Joint Trajectory Design and User Scheduling of Aerial Cognitive Radio Networks
Hongjiang Lei, Haosi Yang, Ki-Hong Park +3
Unmanned aerial vehicles (UAVs) have been widely employed to enhance the end-to-end performance of wireless communications since the links between UAVs and terrestrial nodes are li…
A New Rate Splitting Strategy for Uplink CR-NOMA Systems
Hongwu Liu, Zhiquan Bai, Hongjiang Lei +3
In uplink non-orthogonal multiple access (NOMA) channels, the existing cooperative successive interference cancellation (SIC) and power control (PC) schemes lack the capability of…
On the Secrecy of UAV Systems With Linear Trajectory
Gaofeng Pan, Hongjiang Lei, Jianping An +2
By observing the fact that moving in a straight line is a common flying behavior of unmanned aerial vehicles (UAVs) in normal applications, e.g., power line inspections, and air pa…
On the Physical Layer Security of a Decode and Forward Based Mixed FSO/RF Cooperative System
Dipti R. Pattanayak, Vivek K. Dwivedi, Vikram Karwal +3
In this letter, the secrecy performance of a mixed free space optics (FSO) and radio frequency (RF) system is analyzed from physical layer security (PHY) perspective. In this scena…
Secrecy Outage Analysis for Cooperative NOMA Systems with Relay Selection Scheme
Hongjiang Lei, Zixuan Yang, Ki-Hong Park +4
This paper considers the secrecy outage performance of a multiple-relay assisted non-orthogonal multiple access (NOMA) network over Nakagami- fading channels. Two slots are util…
