Predict Channel Performance Using S-parameter Extrapolation

In this work, we demonstrate using three s-parameter extrapolation methods, i.e., S-matrix-based, SDD21-based, and fitted-SDD21-based, to predict the performance of a high-speed channel. The critical points in applying the s-parameter extrapolation are discussed and the results obtained are compared. The study shows that the s-parameter extrapolation is doable provided certain conditions are fulfilled.
