The Matched Window Reassignment

Sandsten, Maria LU ; Brynolfsson, Johan LU and Reinhold, Isabella LU (2018) p.2340-2344
Abstract
In this paper we calculate reassigned spectrograms
using the envelope of an arbitrary signal as matched window. We
show that the matched window then give the perfectly localized
reassignment for any time-translated and frequency-modulated
transient signal with corresponding envelope. The general expressions of the corresponding scaled reassignment vectors are
derived and the matched window reassignment is evaluated
for time-frequency localization as well as for classification. The
results show that the accuracy in time- and frequency location
is high also when the signal envelope deviates from the matched
window and when the SNR is reasonable large. The classification
performance based on the matched... (More)

Rényi entropy is robust to signal envelope deviations as well as
to disturbing noise. (Less)
