Reducing the number of iterations in the WCIP method in case of space excitation

The WCIP method (Wave Concept Iterative Process) is a numerical method used for modeling electronic HF circuits (High Frequency). In some cases, this method requires a big number of iterations to converge to the optimal result. That's why it needs much computing time. For this, we use an autoregressive an adaptive filter to reduce the number of iterations calculated by this method.
