Design scheme of TD-SCDMA coverage for high-speed railway from Guangzhou to Hongkong
摘要
广深港高速铁路乘坐人群主要是商务和公务人士
为使旅客可在时速高达250km/h的高速列车上享受丰富的3G服务
铁路全程进行TD信号覆盖
本文重点介绍高速铁路TD信号覆盖最需要解决的多普勒效应和快速切换带来的不利影响
对隧道内TD信号覆盖的设计方案进行简单分析
最后从网络优化方面提出对高铁进行信号覆盖的几点建议。
Abstract
This article focuses on the adverse impact brought by the doppler frequency shift and rapid handover
which are very important questions for the high-speed railway to assure the TD signal coverage.Also
the article simply analyses the design scheme of the TD signal coverage in tunnel.Finally this article provides a few suggestions from the point of view of the network optimization.
