TD-LTE系统天馈演进策略探讨

A Discussion for Evolution Strategy of TD-LTE Antenna System

本文首先对TD-LTE(D频段)与TD-SCDMA(F、A频段)共用天馈线的性能进行了理论分析,针对共用天线引起的控制信道(无波束赋形)和业务信道性能变化进行了系统仿真验证,随后针对TD-LTE室内分布的天馈形态进行了分析,最后针对TD-LTE天馈线的工程实施方案进行了探讨。

Firstly, the performance of shared antenna system including TD-LTE （D band） and TD-SCDMA （F, A band） was theoretically analyzed, besides this, a system simulation aiming at the performance change of control channel （without beamforming） and traffic channel caused by sharing antenna is made. Subsequently the antenna pattern aiming at TD-LTE indoor distribution system is analyzed, finally a discussion for the project implementation of TD-LTE antenna system are discussed.
