In this paper, we analyze the Shannon capacity of the opportunistic relaying technique in amplify-and-forward cooperative systems over Rayleigh fading channels under outdated channel information. Closed-form expressions are derived for the average channel capacity and outage probability. Using numerical evaluations the performances of different cases are compared to evaluate and quantify the effects of outdated channel information on the channel capacity and the outage performance.
