【 摘 要 】

In this study, primary user (PU) interference in a cognitive amplify-and-forward relay network is considering over a Nakagami-m fading channel, and the outage probability is derived for the secondary users. This PU interference has not previously been considered in the literature. Results are presented which show that PU interference can significantly degrade secondary user performance, and thus should be considered in the design of a cognitive radio network.
