中文摘要：

在认知无线网络环境下，为高效合理地进行频谱资源的管理与分配，引入经济活动中的预售机制，提出了基于预售机制的动态频谱管理（P~DSM）方案。针对方案频谱市场分级架构及运作流程进行详细阐述，对方案中基础市场（BM）频谱分配细节进行了基于超模博弈方法的分析与仿真，实验结果表明，该方案能有效的减少时延，加快收敛速度，提高频谱利用效率。

英文摘要：

With the rapid development of wireless communication technologies, the contradiction between spectrum supply and demand has become increasingly serious, In the cognitive radio network environment, to manage and allocate the efficient spectrum, the presellkng mechanism in economic activity is introduced and game-based dynamic spectrum management in preselling mechanism （PS-DSM） are pro- posed. Then the framework of the PS-DSM and its work flow are elaborated in details, then basic market （BM） spectrum allocation de- tails is illustrated in supermodel game-theory analysis and simulation. Simulations show that the PS-DSM program can not only reduce the delay, accelerate the convergence rate, but also improve the spectrum utilization efficiency.
