Title:Spectral Reassignment for Improved Estimation
Abstract:
The spectral reassignment method utilizes phase information in the Fourier transform to
realign energy in the time-frequency plane. This has the impact of improving upon the
precision of frequency estimation for high SNR signals of interest. The technique,
first discovered decades ago, has found renewed interest in its application, partly
because of the significant improvement in processing power now available. This talk
will present some of the essential ideas regarding the spectral reassignment technique
and discuss its utility for several applications. Comparisons with other techniques
will also be provided.
