基于灰色系统理论对GSM-R网络进行干扰评估的研究

Interference Evaluation of GSM-R Network with Gray System Theory

GSM-R(global system mobile for railway)网络是高速列车的信息传输中枢,为了保证其处于良好状态,必须对该网络的干扰情况进行准确的评估。本文基于灰色系统理论对GSM-R网络的干扰进行综合评估,可以有效克服传统干扰评估方法的缺点。首先阐述了GSM-R网络干扰评估的重要性和灰色系统理论基本原理;接着针对GSM-R网络的相关性能指标,通过灰色关联聚类算法进行分类优化,降低了评估难度;最后通过实例与对比证明了基于灰色系统理论对GSM-R网络进行干扰评估的有效性。

GSM-R network is the information transmission carrier of high-speed railway,in order to ensure that is in good condition,we must evaluate the interference of GSM-R network accurately.Comprehensive assessment of GSM-R network with gray system theory overcomes the shortcomings of the traditional methods.This paper first describes the importance of assessing GSM-R network and introduces the principles of the gray system theory,then presents GSM-R interference-related indicators and analyzes the assessing indicters through algorithm of gray incidence cluster.Finally the example is given in order to prove the effectiveness of assessing interference with cray system theory in GSM-R network.
