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，因其具有广阔的前景而备受关注。认知无线电的支持技术之一是频谱共享。我们关注的事实是，频谱共享中多个决策实体的动态可以通过引入进化博弈论来建模。首先，利用演化博弈论对频谱共享系统进行建模，明确其特征。其次，提出了基于少数博弈的频谱共享系统中的分散式传输调度来管理干扰，结果表明，由于许多发射机的传输定时是自组织的，干扰得到了很好的管理。第三，对移动路由器的自适应控制进行了建模并阐明了其收敛条件。
