An optimally concentrated Gabor transform for localized time-frequency components
Benjamin Ricaud, Guillaume Stempfel, Bruno Torrésani +3
Gabor analysis is one of the most common instances of time-frequency signal analysis. Choosing a suitable window for the Gabor transform of a signal is often a challenge for practi…
