Instantaneous frequency estimation of arbitrary polynomial phase signals is shown to be feasible using higher order time–frequency representations such as L-Wigner distribution and complex time–frequency representation. These new extensions of the iterative cross-Wigner distribution based algorithm are shown to have certain computational advantage as well as noise robustness.
