Abstract

The "Polynomial Phase transform (PPT)", was presented in [l] as a tool for the estimation of the parameters of constant amplitude polynomial phase signals. Extensions of the algorithm have also been proposed in [2] to be able to deal with parameter estimation for multiple components and for time-varying amplitude. While the PPT is computationally efficient and almost statistically efficient at high signal to noise ratio (SNR), it fails catastrophically at low SNR. This paper presents an extension so that the PPT can operate at lower SNRs. The proposed algorithm is iterative: and uses a similar approach to that used for parameter estimation of quadratic phase signals in [3], [4] and [5].

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
