| 摘 要： | 提出了一种选择最大多用户分集MIMO信道调度方法,能在不降低性能的基础上减少反馈负载.每个用户将最大的信干噪比值与设定的门限比较,只有大于门限的值及对应的发射天线序号返回给基站,基站分配独立的信道给最大信干噪比用户.给出了所提方案的系统平均容量和反馈负载量的分析,仿真结果与分析一致.

| Abstract: | An selective maximum multi-user diversity(SMUD)scheduling scheme which can reduce feedback load while preserve most of the capacity performance in MIMO Channels is proposed in this paper.Each user compares its maximum SINR to a threshold only those who fall above it along with the index transmit antenna are sent back to the base station.The base Station allocates independent channels to the users with the highest SINR.Average capacity and feedback load for the proposed method is obtained and shown to match ... |
