摘　　要：频谱共享是认知无线电系统中的关键技术之一,关于频谱共享的模型和算法也是学术界关注的热点。本文将博弈论理论应用到认知无线电的频谱分配中,分析了基于潜在博弈的频谱分配算法,并得到了相应博弈过程的纳什均衡。分析结果表明,该纳什均衡是系统频谱分配的较好的策略点.Spectrum sharing is one of the key technologies in cognitive radio system,and communication experts pay much attention to the model and algorithm for Spectrum sharing.Game theory was applied to cognitive radio spectrum allocation in the paper,spectrum allocation algorithm based on potential game was analysised,and Nash Euilibrium of the game was obtained.The result shows that the Nash equilibrium is the betterl strategy point of spectrum allocation in the system.

关 键 词：频谱共享 博弈论 纳什均衡
