This paper proposed game theory for dynamic spectrum allocation in cognitive radio network.It proposed the spectrum allocation model in cognitive radio based on game theory and proposed a distributed spectrum assignment algorithms based on potential game theory,and obtained Nash equilibrium of the game.The simulation result shows that the algorithm converges to be steady state in a relatively short time,the potential function value achieves maximum,the total interference level of the system achieves minimum,the level of the user's SIR is significantly improved,Nash equilibrium of potential game can be obtained by channel allocation and achieved to improve the purpose of the spectral efficiency.
