Abstract 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.
