A model analysis method of cognitive radio based on game theory

Based on analyzing the physical layer structure, some new algorithms and strategies of cognitive radio, this paper put forward a general analysis method of game theory in cognitive radio and issues which should be paid attention to. In the paper, we introduced a power control model of game theory which built to the total interference level of a minimum system as a target, and validated the feasibility of this analysis in practical application. This paper also discussed a new mechanism of cost function. In the end, the paper makes a summary of the research status of the cognitive radio technology and its future prospects.
