A novel STFT implementation for the analysis of non-stationary jammer interference

Durak, L.; Arıkan, Orhan; Song, I. (IASTED, 2004)

A novel adaptive short-time Fourier transform (STFT) implementation for the analysis of non-stationary multi-component jammer signals is introduced. The proposed time-frequency distribution is the fusion of optimum STFTs ...
Optimal short-time Fourier transform for monocomponent signals

Güven, Hüseyin Emre (IEEE, 2004)

New methods of improving the short-time Fourier transform representation of signals have recently emerged. These methods use linear canonical transforms to bring the signal into a minimal time-bandwidth product form. Here ...
Short-time Fourier transform: two fundamental properties and an optimal implementation

Durak, L.; Arıkan, Orhan (IEEE, 2003)

Shift and rotation invariance properties of linear time-frequency representations are investigated. It is shown that among all linear time-frequency representations, only the short-time Fourier transform (STFT) family with ...
