摘要
为了解决LTE室内MIMO分布系统信号的覆盖问题,本文通过对比分析提出了一种基于有源天线的单馈线MIMO方案。该方案在不改变原有室分系统结构的基础上通过一路馈线实现了LTE完整的MIMO特性,提高了系统性能,解决了实际工程中多馈线安装受限的难题,极大的降低了工程改造成本与周期,具有广泛的应用前景。
In order to solve the signal coverage problems of LTE MIMO indoor distribution system,this paper presents a single feeder MIMO scheme based on active antenna.The program does not change the original chamber subsystems based on the structure achieved through one feeder complete LTE MIMO features,improved system performance,solve more restricted feeder installation problems for practical engineering,greatly reducing the engineered costs and cycle,with a wide range of applications.
