Evaluation of non-linear combinations of rescaled reassigned spectrograms
(2014) 22nd European Signal Processing Conference - EUSIPCO 2014 p.486-490- Abstract
- The reassignment technique is used to increase the localization for signals that have closely located time-frequency components. For Gaussian components the reassignment based on an optimal (matched) window spectrogram will result in a single point where all mass is located. For non-optimal windows, the reassignment procedure can be optimally rescaled to fulfill the single point mass location. Non-linear combinations of spectrograms for different window lengths have previously been suggested, [1], and in this paper an evaluation is made of the performance for different non-linear combinations of optimally rescaled reassigned spectrograms.
