ABSTRACT
Cognitive Radio is the new technology which can optimize the utilization of the frequency spectrum. The Primary User and the Secondary User utilize the same frequency spectrum so that the Signal-to- interference- plus-noiseratio of the Primary User will be reduced. In order to ensure the Quality-of-Service of the Primary User, the Power Control should be done to the Secondary User and the Admission Control should be combined to maximize the number of the Secondary User. In order to ensure the Quality-of-Service of the Secondary User, the Priority Mechanism is adopted to avoid the transmission interruption of the Secondary User. The simulated results show that the system performance is superior to the original algorithm.
