Abstract


Now the existing spectrum allocation has been almost completed, and the new allocation of spectrum will wait a very long time, so the existing spectrum allocation should be reached a higher and reasonable efficiency. This paper is about spectrum allocation algorithm, which is based on game theory and under the study of the spectrum of cognitive radio. The main research work and results are summarized as the following three points:Firstly, paper describes the main theory of cognitive radio and spectrum allocation, focuses on the game theory and its application in cognitive radio, and elaborates three game theory classical model.Secondly, for the spectrum pricing game between the primary user in cognitive radio system, in accordance with the classic Bertrand model and the Cournot model, paper explores a dynamic Bertrand algorithm based on distributed coordination. Theory proves that this algorithm has gotten the stable spectrum pricing strategy, and based on the Nash coordination system utility and fairness also have a good compromise. Simulation data also has shown that the coordination algorithm not only gets close to the optimum effectiveness of the utility, but also improves the fairness among users , finally user’s utility and fairness have a good compromise.Finally, for the mutual interference problem in the game of the cognitive radio system, paper explores a non-cooperative game algorithm based on strict potential game, and proves that it has a stable Nash equilibrium. The algorithm coinstantaneously distributes users’spectrum and power, and make users select the best strategy dynamically. simulation studies have shown that the algorithm has a faster convergence under the premise of ensuring the fairness ,and the final throughput of the system is also greatly improved.
