Time-frequency distribution spectral polynomials for instantaneous frequency estimation

The local autocorrelation function of the time-frequency distribution (TFD), defined by an appropriate kernel, is used to form a spectral polynomial. Some of the roots of this polynomial correspond to the instantaneous frequencies of the input signal. In this paper, we use extended version of Newton...
