Abstract
In this paper, a novel joint relay and destination selection scheme is proposed to enhance the secrecy performance in cooperative single carrier frequency domain equalization (SC-FDE) systems with multiple relays and multiple destinations in the present of a group of eavesdroppers. In particular, we derive the exact and asymptotic closed-form expressions for the secrecy outage probability (SOP) and the asymptotic results demonstrate that in sufficient high SNRs region of main channels, the achievable secrecy diversity gain is L1QK, i.e., the product of the channel tap L1, the number of destination nodes Q and the number of relay nodes K. Analytical results indicate that our proposed joint selection scheme can achieve better secrecy performance compared with that in previous work.
