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