| Résumé : | A new physical model 'VUB1' is proposed to characterize a metallic parallel wire or twisted wire pair. The VUB1 model will be compared with a rational function in the s-domain and with the popular physical model 'BT0' of British Telecom as described in the standards for Metallic Access Networks. The VUB model contains a limited parameter set and is linear and time invariant there were the models used in the standards use more parameters and are semi-empirical, which can lead to non-causal systems. Metallic cable characterization with physical models will be compared with rational functions in the Laplace-domain. A Maximum Likelihood Estimation framework is used in the frequency domain to identify the model parameters. The performance of the models will be compared with a simulation directly based on measurements. © 2001 IEEE. |
