A METHOD OF IDENTIFYING TRANSFER FUNCTION FOR NETWORK BY USE OF M-SEQUENCE CORRELATION

Eiji Nishiyama, Kenshi Kuwanami

Abstract

Monitoring a communication line is significant for broadband, mobile phone and so on. In this paper, we propose a new method for detecting a fault point of communication line by use of M-sequence correlation technique. In this method, detecting signal is used as one or plural M-sequences ( same characteristic polynomial, including normal and reverse mark, synchronized ). At receiving tap, we make same sequence with the input one and take crosscorrelation function between M-sequence and the received signal. We can get transfer functions of plural paths between inputs and a output tap separated from different of delay times on the crosscorrelation function, and from these transfer functions, so fault point is occurred when we compare them.
