Abstract :
Channel correlation has the effect to reduce the sum rate and user capacity of multiuser multi-input multi-output (MU-MIMO) systems considerably. In this paper, receive antenna selection is proposed for uplink MU-MIMO system to maximize the sum rate and to maintain high user capacity over correlated Rayleigh fading channel. Two antenna selection criteria are presented to tradeoff the computational complexity and performance. Capacity based selection criterion (CBSC) provides optimal performance at the cost of high complexity compared with the suboptimal norm based selection criterion (NBSC). Simulation results demonstrate and validate the effectiveness of proposed method compared with conventional MU-MIMO systems.
