In this paper, the authors consider a multi-channel cognitive radio system serving a primary network and a secondary network, and analyze the quality of service and delay-constrained capacity of the secondary network. Specifically, by assuming that a certain amount of resource is exclusively reserved and used on each channel by the primary network, they derive the traffic transportation capacity that is guaranteed to the secondary network. Based on this, they analyze the traffic delay distribution in the secondary network and derive an upper bound on it, which allows them to further obtain a guaranteed capacity of the secondary network in serving traffic with probabilistic delay requirement.
