In order to maximize the throughput of cognitive radio network,a spectrum allocation algorithm of cognitive radio based on supermodel game was proposed,which is taking the orthogonal frequency division multiplexing(OFDM)as the system model.This algorithm brings in a suitable pricing function to evaluate the impact that the cognitive users bring to the primary user.Based on the pricing function,the price punishment was imposed to the cognitive users,and ultimately the inference of cognitive users on the primary user was reduced.Simulation results show that this algorithm can finally achieve convergence,reduce the inference of cognitive users on the primary user and obviously improve the throughput of the system.
