Time-frequency representations (TFR) combine the time-domain and frequency-domain representations into a single framework to obtain the notion of time-frequency. TFR offer the time localization vs. frequency localization tradeoff between two extreme cases of time-domain and frequency-domain representations. The short-time Fourier transform (STFT) [1, 2, 3, 4, 5] and the Gabor transform [6] are the classical examples of linear time-frequency transforms which use time-shifted and
