Abstract

We consider a cognitive radio network where secondary cognitive users communicate with an access point relying on opportunistic transmissions over wireless fading channels. For such a network, it is important to maximize aggregate utility of average user rates under the constraints of average user power budgets and maximum allowable probabilities of… (More)
