- In this paper, we propose a user scheduling scheme to maximize the ergodic capacity of multi-user MIMO uplink systems. The proposed scheduling scheme only considers the use
of the receive correlation matrix of users, not the instantaneous channel state information of users. The proposed user scheduling scheme is applied to collaborative spatial multiplexing systems
specified in the IEEE 802.16e, where the base station receives two user signals at each time slot using two receive antennas. Analytic and numerical results show that the proposed user scheduling scheme outperforms conventional random user scheduling scheme
in terms of the ergodic capacity without loss of opportunity fairness.
