LTE多天线接收增强技术组网分析

Analyses on Enhanced Reception Techniques and Networking of LTE Multi-Antenna

多天线技术的采用是LTE速率成倍提升的关键因素,它通过提高网络的分集增益使得LTE更能满足日益增长的无线数据业务需求。重点分析多天线接收增强技术——四天线接收带来的上行链路覆盖与容量增益,并通过组网试验的方法,深入研究四天线接收相对于两天线接收在不同场景、不同组网方式下的增益情况,由此给出LTE多天线部署的应用建议。

Multi-antenna techniques are the key factor to multiply LTE rate, which satisfy the increasing demands on wireless data services by enhancing diversity gain. As a multi-antenna enhanced reception technique, four-antenna is emphatically analyzed in both uplink coverage and capacity gain. By networking tests, its gain performance is compared with two-antenna in different scenes and networking modes. Finally, corresponding recommendations of LTE multi-antenna deployment are presented.
