摘要
场强测试是评价与衡量高速铁路GSM-R系统网络覆盖状况的主要手段,是无线通信网建设中重要内容之一,贯穿于网络建设的各个阶段.本文从GSM-R无线信号的传播特性出发,以Lee氏定理的研究方法为基础,探讨目前场强测试理论与实践之间存在差距的原因,从理论和实践对我国铁道部规定的4cm标准采样间隔进行了推导和验证.
Field strength measurement is the most effective way in the assessment of high-speed railway GSM-R coverage estimation, it is also one of the main contents of wireless communication network construction, it through each stages of the network construction. This paper began with GSM-R wireless signal propagation characteristics based on research method of Theorem Lee, in order to find out the reasons for the difference between theory and practice in field strength test, the 4 cm standard sampling intervals of China ministry of railways issued had been derived and confirmed theoretically and practically.
