中文摘要：

多输入多输出（MIMO）系统是未来移动通信热点技术之一。单小区多用户MIMO多接入系统性能受限于同信道干扰。该文提出了采用博弈论的分析方法，对系统进行分布式功率控制，优化系统资源配置。仿真结果表明，该文建立的非合作博弈模型是合理的，而分布式功率控制算法也是有效可行的。

英文摘要：

Multiple-input and Multiple-output （MIMO） is a hot mobile communication technology in future. Single cell multiple user MIMO system is interference-limited by cochannel. The contribution of this paper is： game theory is used to analyse the MIMO multiuser system, and a distributed power control algorithm is given to optimize the system resource. The simulation results show that the noncooperative game model is reasonable. And the power control algorithm is found to give a significant performance improvement for the MIMO system when compared with the system without power control.
