| 摘 要： | 分析了分布式移动通信系统中,Rayleigh-lognormal复合信道下,发送分集对下行链路多用户分集的影响,发现基于最大比发送(MRT)和基于选择发送分集(STD)调度算法获得了几乎相同的多用户分集增益。该结论表明,在分布式移动通信系统中,采用基于发送分集的调度方案并不能有效地提高系统的吞吐量。

| Abstract: | The influence of transmit diversity （TD） on multi-user diversity of down links is studied under Rayleigh-lognormal composite channel model in the distributed mobile communication system. It is found that the average throughput of scheduling based on maximum ratio transmit （MRC） is nearly equal to that of scheduling based on selection transmit diversity （STD）. This result shows that scheduling based on riD can not improve the average throughput of the distributed mobile communication system effectively. |
