Abstract :
This letter investigates spectrum-sharing cognitive amplify-and-forward relay networks employing the maximum ratio transmission/maximum ratio combining scheme at the multiple-antenna source-destination pair. It derives closed-form expressions for the ergodic capacity and for the symbol error rate lower bound and its asymptotic value when considering Nakagami-m fading and interference constraints on N primary receivers.
