摘　　要：研究在频谱共享条件下家庭基站双层网络的分布式功率控制策略.将宏基站所能承受的干扰限度视为家庭基站的可分配资源,家庭基站以竞价形式对其"购买",从而构成宏基站与家庭基站以及家庭基站用户之间的博弈模型.分析了该博弈过程中纳什均衡解的存在性和惟一性,并给出了在非合作模式下指导家庭基站用户进行理性竞争的分布式功率调整算法.最后,通过仿真实验验证了所提出算法的有效性.The distributed power control strategy is investigated, which works in the spectrum-sharing femtocell two-tier network. The aggregate interference threshold, which the macrocell can tolerant, is regarded as the allocated resource. The femtocell users compete with each other and purchase it. So the Stackelberg game model of the macrocell and femtocell is built, and the non-cooperative game model of femtocell users is established. Then the existence and uniqueness of Nash equilibrium in the non-cooperative game are analyzed. The distributed power adjustment algorithm is given to guide the femtocell users to compete with each other rationally in non-cooperative pattern. The simulation examples are presented to verify the effectiveness of the proposed algorithm.
