摘要

通过定量分析利用随机波束成型技术的多用户分集系统的吞吐率性能

在此基础上提出利用公共信道部分反馈信道信息的多用户分集方案并分析了它的性能

证明通过设置合理的门限

部分反馈信道度量几乎不降低系统吞吐率

但可以大量节省上行反馈的开销

当采用合适的多址方式

在一定带宽下

系统可以容纳更多的用户。

Abstract

By investigating the throughput performance of multiuser diversity system with random beamforming

a multiuser diversity scheme with partial feedback of channel metric on common uplink channel were proposed. Performance analysis proves that with proper threshold

partial feedback of channel quality can pay much less for uplink feedback with little decrease of system throughput

which means that the system will accommodate more user within given bandwidth.
