Rekursive Wigner-Spektralanalyse höherer Ordnung

An appropriate spectral analysis of nonstationary signals requires time-variant methods. Going out from the approach of time-variant spectral and bispectral analysis based on the adaptively recursively estimated 2nd and 3rd order cumulants, an optimised algorithm is presented. It can be generalised as special kind of smoothed Pseudo-Wigner-Distribution. The benefit is the recursive calculation of its kernel . Therefore, the method is convementfor higher-order spectral analysis of ongoing signals.
