%X The author develops a new non-cooperative game dynamic spectrum allocation scheme. This scheme considers multiple cellular service providers and D2D service group which have the cognitive ability, and uses the Bertrand game theory to solve the problem of user spectrum allocation. The utility function of D2D service group and cellular service providers are improved respectively. This article also puts forward optimal pricing of cellular service providers and dynamic price adjustment strategy of D2D service group. Furthermore, the existence of a Nash equilibrium state and the convergence of the algorithm are proved. By simulation and experiment, the impact of different numbers of cellular users and different learning factors on the performance of the proposed scheme is analyzed. Compared with existing ones, this scheme improves both the spectrum utilization and system fairness.
