… We study relay selection for an underlay CR network that uses fixed-power AF relays
subject to an average interference constraint. We focus on the classical AF relaying protocol [7] …

… are each subject to peak interference constraints. A multi-relay selection scheme in which
the total interference power from all the transmitting relays is constrained is considered in [10]. …
