Modeling alien-line impedance mismatch in wideband vectored wireline systems
article
Sudden changes of channel coefficients in a wideband vectored wireline system (such as G.fast) due to changes in the terminating impedance of lines outside the vectored group can seriously degrade stability and throughput. This letter presents a model that predicts the impact of termination mismatch based exclusively on crosstalk data for the properly-terminated state. Experimental results confirm a tight fit between model and measurements. The model allows analysis of system performance and stability without dedicated crosstalk measurements for mismatch cases.
