Title: A performance analysis of polynomial FM signals
Author: Barkat, B; Boashash, B; Zoubir, A.M.
Abstract: The polynomial Wigner-Ville distribution was designed as an optimal tool for characterising the spectral contents of a signal whose phase is a polynomial of a certain order. In this contribution, the peak of the polynomial Wigner-Ville distribution is used to estimate the instantaneous frequency of a polynomial phase signal. A general expression for the asymptotic variance is derived for the estimator, and a statistical comparison with a parametric method for estimating the instantaneous frequency, using the high-order ambiguity function, is established.
Description: This is preliminary work that later appeared in a journal paper by Boashash and Barkat. A software package that calculates IF estimates and TFDs can be downloaded from the web site: www.time-frequency.net
