文章首先研究了TDD-LTE相同频段部署情况下,高速铁路通信专网受到高速铁路沿途部署的宏蜂窝网络干扰而引起的高铁通信专网性能损失情况。根据高速铁路通信专网场景的特点,文章采用了半动态的仿真方法进行研究。随后,针对高铁专网受到干扰的结果,文章提出三种基于天线改进的降干扰方案并给出方案改进后的干扰结果。相关研究对高速铁路通信网络的建设和规划具有良好参考意义。

This article firstly studies the interfer- ence between High-speed rail private network and macro cell public network under TDD-LTE system. According to the characteristic of High-speed rail private network, this article takes the semi-dynamic simulation method to study. Then, in view of the in- terference result, this article puts forward three in- terference reducing methods based on antenna changing and also offers interference result after re- ducing. The above study shows great reference val- ue to constructing and planning of telecommunica- tion network of High-speed rail.
