摘要: 研究了在保护授权链路的前提下认知无线电网络(CRN)的频谱优化分配问题。基于博弈论提出了一种新型的频谱分配模型,设计了一种保护授权链路的快速收敛的频谱分配算法(FCAPLL)。仿真分析证明,FCAPLL算法能在保护授权链路的前提下对认知无线电(CR)链路进行最优化频谱分配,有较快的收敛速度;同时仿真给出了网络性能参数与比例因子的关系,为FCAPLL应用于不同性能要求的CRN提供了依据。

Abstract: The optimization of spectrum allocation based on protecting licensed link in Cognitive Radio Network is researched. A new model of spectrum allocation based on game theory is presented and a fast convergent spectrum allocation algorithm for protecting licensed link is proposed. The simulation analysis shows that the algorithm has fast convergent speed and achieves spectrum allocation optimization of cognitive radio link based on protecting licensed link; the simulation also presents the relation between network performance parameters and proportional factor, which provides a basis to algorithm application for cognitive radio network with different performance requirement.
