| 摘 要： | 提出了基于博弈论的认知无线电静态频谱共享模型,研究多个次级用户竞争一个主用户系统的空闲频谱。建立了基于自我约束机制的主用户系统的效益函数,主用户系统兼顾自身频谱需求与不浪费剩余的空闲频谱两方面来确定合适的价格,并引入了动态频谱共享算法,次级用户能不断调整自己的策略最终趋于纳什均衡,最大化自身效益。

| Abstract: | A game-theory based static spectrum sharing model is proposed for cognitive radio,which supports multiple secondary users competitively sharing one primary user system's idle spectrum.The primary user system's benefit function based on Self-discipline mechanism is established.Reasonable price is determined considering both primary user's spectrum demands and no wasting of the remaining free spectrum.Dynamic spectrum sharing algorithm is introduced,in which the secondary users can continuously adjust their s... |
