Instantaneous Frequency Estimation of Monocomponent Signals
2011Instantaneous frequency (IF) is a key parameters which provides crucial information about time-varying spectral changes in a non-stationary signal. The IF estimation error exhibits variance and bias dependant on the TFR analysis window width such that the bias increases and variance decreases as the window length increases.

Instantaneous Frequency Estimation of Multicomponent Signals
2011One of the key parameters which provides important information about time-varying spectral changes in a non-stationary signal is its instantaneous frequency (IF). The most challenging IF estimation problem is to find the individual component IF of a multicomponent non-stationary signal corrupted by noise.
