An update on Gabor deconvolution

Gary F. Margrave, David C. Henley, Michael P. Lamoureux, Victor Iliescu, Jeff P. Grossman

Gabor deconvolution has been updated and a new ProMAX module is released. The updates are: (1) a new method of spectral smoothing called hyperbolic smoothing; (2) a Gabor transform using compactly supported windows that improves run times by one to two orders of magnitude; and (3) a post-deconvolution time-variant bandpass filter whose maximum frequency tracks along a hyperbola in the time-frequency plane. We discuss the technical details of these improvements and present an overview of the new ProMAX module.
