“…This original method will be employed in this paper and is briefly discussed in Appendix A. Other EPSD estimation methods are beyond the scope of this paper and only summarized as follows: (1) the wavelet transform [18], (2) the positivity constrained deconvolution procedure based on the Wigner-Ville distribution [19], (3) time-varying AR/ARMA models [20], (4) the multifilter technique [21] and (5) the preperiodogram method [22].…”

“…It allows a physically meaningful time-evolving spectral density function to be defined -with frequency having its usual meaning -for so-called "semistationary processes." In addition to Priestley, estimation of the ES has been condidered by many others [12], [17], [18], [22], [30], [31], [32]. (There have also been generalizations and modifications of the ES [1], [11], [34] directed to the analysis of deterministic signals and involving instantaneous frequency.…”

“…Dabei wird den Koeffizienten im Fourierspektrum eine schwache Zei-tabhängigkeit zugestanden. Allerdings ist die Schätzung evolutionärer Spektren schwierig und noch Gegenstand aktueller Forschung [23,43,19]. Die Verallgemeinerung der evolutionären Spektren durch die Einführung einer zeitabhängigen Phase wurde von Detka et al vorgeschlagen [20].…”
