Open publisher page 0 citations

Abstract

A novel iterative parameter estimate method for Polynomial Phase Signal is established based on Zero-Extremum Crossing Test (ZECT) and Lest-Square (LS) principle. The ZECT is developed firstly. Then the Polynomial Fitting (PF) for the phase parameters and the linear fitting for the varying amplitude are performed alternatively. The obtained date are inserted into the next step estimation. The efficiency of the proposed method is approved through an example signal in different noisy conditions.
