Abstract
Investigated is the outage performance of cognitive wireless relay networks in a fading environment, where the secondary users including the source and relays may take advantage of a frequency band of a licensed (primary) user by opportunistically transmitting with high power as long as the interference it incurs is not deemed harmful by the licensee. The relation between the secondary channel performance and the interference inflicted on the primary user is quantified.
