Interference Assessment on the Circuit Domain in GSM-R Networks by Grey Clustering and Analytic Hierarchy Process
In the high-speed railway communication networks, interference is quite complicated and serious interference can even ruin the security of trains. So how to evaluate the effect is becoming more and more important. Both grey clustering evaluations and analytic hierarchy process are an effective comprehensive evaluation theory. In this paper, we apply the theory of grey clustering evaluations and analytic hierarchy process to assess the interference of the circuit domain in GSM-R networks and make a comprehensive evaluation on interference. Based on the theory of grey clustering evaluations, the interference is sorted into rough groups. Then further classification of the interference can be obtained. The results show that grey clustering evaluations combined with analytic hierarchy process can provide the reliable interference evaluation in the railway services.
