摘要：
In this paper, we study the secrecy outage probability (SOP) of an opportunistic relay selection scheme where an optimal relay is selected based on the delayed feedback from the multi-antenna destination. We present a new exact closed-form expression of the SOP, and two kinds of asymptotic form of SOP are further derived to explicitly show secrecy performance. In addition, we show that the SOP can be reduced by increasing the number of relays through analysis and simulation results. An important result show that the secrecy diversity order of the system has nothing to do with the number of relays with outdated CSI.
