摘要
在频谱资源共享条件下,Femtocell网络和Macrocell网络构成的双层网络间必然存在干扰。文中研究了功率控制在干扰抑制方面的作用,使用非合作博弈模型描述系统,对基于Stackelberg博弈的功率控制方法中的纳什均衡解进行分析证明,并在此基础上结合一种优化Femtocell性能的链路保护方法,进一步减少未满足信干噪比(Signal to Interference and Noise Ratio,SINR)要求的Femtocell用户设备(Femtocell User Equipment,FUE)数量。仿真结果表明,改进算法能达到预期效果并有效提高了系统性能。
There must exist interference in the two-tie networks of Femtocell and Macrocell when they share the spectrum resource. In this paper ,emphasize the study on the effect of power control to interference suppression by using non-cooperative game pattern to describe the system. Based on the analysis of the Nash equilibrium in Stackelberg game,a link protection method which optimizes Femtocell performance is combined to decrease the number of FUE not meeting the SINR requirements. Simulation results show that the modified algorithm can achieve the desired results and effectively improve the system performance.
