Cognitive radio, which learns surrounding radio environment and adaptively transmits, has attracted much attention due to its promising capability. One of enabling technologies for cognitive radio is spectrum sharing. We focused on the fact that dynamics of multiple decision-making entities in spectrum sharing can be modeled by introducing evolutionary game theory. First, the spectrum sharing system is modeled by using evolutionary game theory and its characteristic is clarified. Second, decentralized transmission scheduling to manage interference in the spectrum sharing system is proposed based on minority game, and it is revealed that the interference is well managed because the transmission timings of many transmitters are self-organized. Third, adaptive control for mobile routers is modeled and its convergence condition is clarified.

认知无线电能够学习周围的无线电环境并自适应地进行传输，因其良好的性能而受到广泛关注。认知无线电的使能技术之一是频谱共享。我们专注于这样一个事实，即多个决策实体在频谱共享的动态可以通过引入进化博弈论建模。首先，利用演化博弈理论对频谱共享系统进行了建模，阐明了频谱共享系统的特点。其次，基于少数者博弈提出了频谱共享系统中干扰管理的分散式传输调度方法，并揭示了由于多个发射机的传输时序是自组织的，因此干扰得到了很好的管理。第三，建立了移动的路由器的自适应控制模型，阐明了自适应控制的收敛条件。
