Abstract:

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.

Key words: GSM-R network, interference evaluation, gray system theory, gray cluster
