) 摘要: FDD-LTE下行有两种MIMO方案:传输分集和空间复用
传输分集的每根天线间的信号具有一定的相关性
传输分集提高了通信的可靠性
空间复用提高了通信的有效性
传输分集
空间复用的每根天线的数据具有独立性
) Abstract: There are two options in LTE MIMO downlink, transmit diversity which improves the reliability of communications and spatial multiplexing which increases communication effectiveness
Signals between each antenna have a certain relevance in transmit diversity, while data in spatial multiplexing with each antenna independence, no correlation, but it increases the capacity of the system
So their scene of usage is not the same
This paper discusses 2 MIMO scheduals
Keywords: FDD-MIMO; transmit diversity; spatial multiplexing 下载PDF阅读器 PDF全文下载: 初稿 ( 224 ) 作者简介: 方秋巳 1984
