EXPERT SYSTEM FOR THE IDENTIFICATION AND CLASSIFICATION OF THE LOCAL LOOP
Leo Van Biesen, Patrick Boets, Frank Louage, Tom Bostoen
Abstract:
The Expert System, which is described in this paper, constitutes a fundamental unit of a general measurement system, which is capable to perform an xDSL (arbitrary Digital Subscriber Line) loop qualification by means of time-domain reflectometry (TDR).
The goal of the measurement system is to estimate the theoretical channel capacity of the local loop, which con-nects the customer premises (CP) to the central office (CO), based on TDR (time-domain reflectometry) measurements and noise PSD (Power Spectral Density) measurements at the CO. These measurements are processed using advanced digital signal processing (DSP), artificial intelligence (AI), and system identification to estimate the loop transfer function and noise PSD at the CP, which are needed for the estimation of the capacity.
