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.
Abstract:
 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 per-formance is combined to decrease the number of FUE not meeting the SINR requirements. Simulation results show that the modified algo-rithm can achieve the desired results and effectively improve the system performance.
