Fig. 4

Effects of Nrand and Niter in the UKF method for the complex-valued signal G(z). Four figures show the computation time and \(E_{N_{\text {decom}}}\) at the 20th decomposition level as well as the mean and the standard deviation of the absolute differences between EN of the conventional method and the UKF method at first 20 decomposition levels for different values of Nrand and Niter
