| 摘 要： | 当认知无线电网络以"衬底式"(Underlay)的方式与主用户网络共享频谱时,需要对认知用户进行功率控制,以确保认知用户在不干扰主用户的前提下,公平地共享认知频谱资源。利用博弈分析的方法,设计了一个基于链路增益因子的代价函数,并据此提出了一种新的非合作功率控制博弈算法。仿真结果表明,该算法的均衡结果既改善了用户的帕累托(Pareto)性能,又提高了链路增益较差的用户的吞吐量,实现了网络资源的平等共享。

| Abstract: | When cognitive radio (CR) network coexists with primary network by underlay, in order to guarantee primary users avoiding interference and also ensure cognitive radio sharing spectrum fairly, it is necessary for cognitive radio to perform power control. In this paper,an original pricing function with path gain is designed and a novel non-cooperative power control game algorithm via game theoretic is proposed. Simulation shows that the novel algorithm improves the pareto efficiency and enhances the system throughput,and also realizes resource allocation equality in cognitive radio network. |
