Abstract
In Rayleigh fading channels, a novel full-duplex destination jamming with optimal antenna selection (FDJ-OAS) scheme is proposed to improve the secrecy performance of the untrusted relay system with multiple-antenna destination. The traditional half-duplex destination jamming scheme and the nonjamming scheme both combined with OAS are presented to compare with FDJ-OAS. The approximate closed-form expressions of ergodic achievable secrecy rate and optimal power allocation factor for FDJ-OAS are significantly derived in the large-scale antennas analysis. Furthermore, simulation results show that, the analytical curves match well with the simulation curves, and the FDJ-OAS is superior to the other two schemes.
