In this paper, we study the secrecy capacity of the proposed transmission scheme. It is provided that the SNR at the selected best relay, destination and eavesdropper are same due to the symmetrical setup. The outage probability is considered here to evaluate the performance of such a secrecy communication system. Then the system will be extended into outdated channel state information (CSI) scenarios. The correlation coefficients between the actual and outdated channel will influence the system performance. The closed-form expressions of the achievable outage probability will be derived to demonstrate the performance of the proposed secure transmission scheme, and numerical results are presented.
