Abstract
This paper presents a power allocation scheme based on non-cooperative Game theory for multi-user multi-input multi-output ( MU-MIMO ) antenna systems. The game scheme uses the signal-to-leakage-and-noise ratio( SLNR) of users in the system as a guide of power allocation and fairness parame-ter setting,furthermore establishes a game model to ensure users’ Quality of Service( QoS) and fairness,as well as proves the existence of Nash equilibrium( NE) . Secondly,considering the influence of channel esti-mation error,it proposes an iterative algorithm based on sliding model to update allocated power in order to meet the minimum QoS requirements among all users. Simulation results show that the scheme can improve the system throughput compared with the existing schemes in the presence of channel error.关键词
