博弈论在感知无线电决策机的应用研究

Application research of game theory in decision maker of cognitive radio

为了使决策机进行策略分析,得到最优的策略,对感知循环、博弈理论以及基于博弈的感知无线电决策机进行了分析。对感知无线电博弈模型中的游戏者、行为、收益等做了相应定义,并针对Neel的决策模型的局限进行了研究。对于多游戏者、多行为、以及多均衡等问题,Neel模型不能很好解决。通过博弈案例的求解分析了多纳什均衡解情况,说明只依靠博弈理论无法得到最优策略,并提出了解决问题的思路。

To get the best strategy, cognitive cycle, game theory and decision maker based on game theory are analyzed. The player, action and utility ofcognitive radio model based on game theory are defined. The limitation ofNeel＇s CR model is studied. Neersmodel cannot solve multi-players, multi-action and multi NE problems. To prove the multi NE instance, two cases of game theory are explained. Only rely on game theory, the best strategy cannot be get. The propose for improvement is studied.
