With cognitive radio technology, secondary users may use the spectrum holes unused by primary users and as a result the efficiency of spectrum utilization can be improved. In order to maximize the total profit of all secondary users, a Nash bargaining solution is proposed based on cooperative game. While considering the minimum rate demand of secondary users, an improved approach based on the Nash bargaining in cooperative game is proposed to maximize the total profit between all the secondary users. The simulation results show that the minimum QoS requirement of the secondary users is guaranteed, the total profit of all secondary users and the system's fairness can be improved comparing with based on non-cooperative game approach.
