摘要

提出了一种适用于Femtocell网络的博弈式频率复用算法。在Femtocell网络中，首先Femtocell基站通过感知其无线环境选择临时子频带，然后通过对分簇后的 Femtocell 网络执行簇内协调和簇间博弈两步算法，消除相邻Femtocell之间的频谱冲突，使Femtocell网络合理地复用频谱资源。在Femtocell随机部署的网络中，该方法解决了Femtocell网络中的频谱冲突问题。仿真表明，采用该算法后，Femtocell网络的频谱冲突得到有效改善，Femtocell系统平均信道容量明显提高。

Abstract

A game-theoretical frequency reuse algorithm has been proposed for Femtocell network.Firstly

each Femtocell tries to get an available sub-band by sensing its radio circumstance.Then

inner-cluster frequency collisions are avoided by implementing a negotiation mechanism.Lastly

each cluster is regarded as a game player to get the largest utility by using its optimal strategy.Despite Femtocell base stations are randomly installed by users

the proposed method performs well in Femtocell network.Simulation results show that frequency collisions are dramatically reduced and the average capacity of Femtocells is considerably enhanced.
