Physical layer security of NOMA-D2D cooperative wireless system by Yifan DING, Guangqiu LI, Hui LI

“…Aiming at the physical layer security (PLS) application requirement of massive user equipments access in the future, the PLS model combining with non-orthogonal multiple access (NOMA), device-to-device (D2D) and relay cooperation was proposed.The model was composed of base station with transmit antenna selection (TAS), NOMA far cellular user of base station and D2D transmitter, D2D receiver and passive eavesdropper, the D2D transmitter was also assumed two roles of NOMA near user of base station and decode-and-forward relay.The approximate expressions for the secrecy outage probability, non-zero secrecy capacity probability and asymptotic secrecy outage probability of NOMA-D2D cooperative wireless system under two TAS schemes were derived by using Gaussian-Chebyshev Quadrature theorem.Numerical and simulation results verify the accuracy of PLS performance analysis of NOMA-D2D cooperative wireless system.The results also show that increasing the power allocated to far cellular user under constant total power of base station can effectively improve PLS performance of NOMA-D2D cooperative wireless system.…”

Physical layer security of modify-and-forward cooperative D2D networks based on transmit antenna selection by LIU Huizhi, LI Guangqiu, ZHANG Yajuan, YE Mingzhu, GAO Hui

“…The D2D transmitter equipped with multiple transmit antennas which adopted TAS technology, then the antenna with the maximum signal-to-interference-plus-noise ratio between the D2D transmitter and MF relay link was selected to send signal. The relay used MF protocol to modify the decoded legal information before forwarding, to avoid passive eavesdropper decoding the legitimate information sent at this stage, which improved the PLS performance of D2D network. …”
