Abstract :
In this paper, we aim to evaluate the sum-rate performance of ZFB MIMO broadcast system with a finite number of users, rather than study the scalability of sum rate with an extremely large number of users as other existing work. We provide an approximation technique for evaluating the sum rate of the ZFB MIMO broadcast system with exhaustive user selection (the optimal selection policy).
