MIMO 的 LTE 实施

智能天线技术多路输入多路输出(MIMO)技术对 LTE 至关重要,它能够最大限度提高系统容量并提供高数据速率。设计方案包括 2 个发射机 × 2 个接收机和 4 个发射机 × 4 个接收机两种。上行链路与下行链路的调制方案是不同的。上行链路采用单载波频分多址(SC-DFMA)调制,属于 OFDM(正交频分复用)方案的一种,下行链路采用 OFDMA(正交频分多址)调制。

设计 LTE 标准的一个主要动力是为了降低终端或移动设备的成本。因此考虑尽量减少多用户多路输入多路输出(MU-MIMO)移动设备上的实际发射天线数量。

在草案完成之后,该标准仍在演进,标准的细节不断变化。参见本网页上列出的应用指南和培训活动,以便了解该技术的最新发展,并学习有效的设计和测试技术。
