A novel user scheduling for multiuser MIMO systems with Block Diagonalization

In order to exploit multiuser diversity in multiuser MIMO systems with Block Diagonalization, A novel multi-user scheduling algorithm, guarantee both the fairness between users and higher capacity of the system, is proposed in this paper. We provide a number of different scheduling schemes and compare them in the terms of average capacity and the fairness as a function of the number of users. Numerical results show that our algorithm can make perfect tradeoff between fairness and capacity.

为了在采用块对角化的多用户多输入多输出（MIMO）系统中利用多用户分集，本文提出了一种新颖的多用户调度算法，该算法既能保证用户间的公平性，又能提高系统容量。我们提供了多种不同的调度方案，并根据平均容量以及作为用户数量函数的公平性对它们进行了比较。数值结果表明，我们的算法能够在公平性和容量之间实现完美的权衡。
