LoopExplorer: Accurate identification op the telephone line system of a client for xDSL communication

Project Details


The goal of the project is to estimate the theoretical channel capacity of the local loop, which connects 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 digital transmission capacity. State-of-the-art measurement techniques will be explored to extend the reach of TDR towards the longest loops. The project consists of fundamental research.
