本文主要是基于认知无线电频谱共享的现状，结合着在经济学中得到广泛应用的博弈模型，提出了一种单卖家多买家的频谱共享模型，并在此基础上分析了其静态模型和动态模型的闭式解，并进行了仿真实现。很具有参考价值。-This article is based on the cognitive status of the radio spectrum sharing, combined with widely used in economics, game model, a single seller and more buyers of spectrum sharing model, and based on the analysis of the static model and the dynamic model of the closed form solution, and a simulation implementation. Is a reference value.
