Abstract

With the development of the communication industry, the spectrum scarcity problem is appearing. Cognitive radio is a popular wireless communication technology. it can solve this problem efficiently[1].In the conventional model .we assume that the occupancy state of the primary user is constant ,which is either active or idle . However, the primary user can be allowed to depart and arrive at the licensed channel randomly .So we propose a new model where the state of the primary user is able to change in the whole frame .Then we compare the two model in the system throughput, and we find that the new performance when the primary user changes it state at any time is taken into account is worse than the conventional network .It means that the network performance is related to the primary user traffic intensity.
