TD-LTE双流波束成形探讨

Research on TD-LTE dual beam forming

针对TD-LTE R9阶段新增加的TM8(双流波束成形)技术,本论文从原理分析上给出了TM8的实现基本原理,以及相较于TM3/TM7等传输模式的优缺点。结合实际测试情况,分析了TM8在现网中的性能,并给出了TM8的应用建议,希望为TD-LTE的建设与应用方面提供一些借鉴。

For the R9 stage of TD-LTE, there＇s a new technology TM8 （double beam forming）. This paper analyzes the basic principles of TM8,and gives the advantages and disadvantages compared the mode of TM3/7. By analyzing the TM8＇s performance in the current network, this paper gives suggestions about the TM8 applying in the network, in order to provide some reference for the construction and application of the TD-LTE.
