Executive Summary

In conventional multi-user MIMO systems, Shannon capacity has been used mostly as the performance measure for user selection. In this paper, the authors propose two new MIMO scheduling techniques based on BER instead of capacity as the performance measure for rate maximization with target BER. One of the key contributions of this paper is to use BER instead of capacity as the user selection metric, and another is the novel power allocation techniques considering user scheduling for the rate maximization strategy. Simulation results show that the proposed BER based algorithms produce higher rate compared to the conventional capacity based user selection algorithm with much lower computational complexity as well as the schemes meet target BER.
