Instantaneous Frequency Estimation of Multi-component Non-Stationary Signals using Multi-view Time-Frequency Distributions Based on the Adaptive Fractional Spectrogram
( IEEE , 2013 , Article)This letter presents a novel algorithm to compute the instantaneous frequency (IF) of a multicomponent nonstationary signal using a combination of fractional spectrograms (FS). A high resolution time frequency distribution ... -
Multi-component instantaneous frequency estimation using locally adaptive directional time frequency distributions
( John Wiley & Sons, Ltd. , 2015 , Article)This paper presents a locally adaptive time-frequency (t,f) method for estimating the instantaneous frequency (IF) of multi-component signals. A high-resolution adaptive directional time-frequency distribution (ADTFD) is ... -
A nonparametric feature for neonatal EEG seizure detection based on a representation of pseudo-periodicity
( Elsevier Ltd , 2011 , Article)Automated methods of neonatal EEG seizure detection attempt to highlight the evolving, stereotypical, pseudo-periodic, nature of EEG seizure while rejecting the nonstationary, modulated, coloured stochastic background in ...
