在分析高速列车系统对无线通信系统需求的基础上,阐述了在高速环境下对无线通信系统进行评估的意义和重要性。根据我国高速铁路特点及需求,提出我国GSM-R无线通信网络指标评估体系的分层模型及各层指标构成。探讨了评估流程,对指标映射以及评估结果分析中用到的主要成分分析、回归分析数学模型方法进行了介绍。
Based on the analysis of the demand of high-speed train system for wireless communication system, the significance and importance of evaluating wireless communication system in high-speed environment are expounded. According to the characteristics and demands of China’s high-speed railway, this paper presents a hierarchical model of the evaluation index system of GSM-R wireless communication network in our country and the composition of each level indicator. The assessment process was discussed. The main components analysis and regression analysis mathematical model used in the index mapping and evaluation of the results were introduced.
