Abstract

This paper deals with the closed-form recursive estimation for parameters of almost periodic moving average (APMA) signal using higher order cyclic-statistics.Two groups of representation formulas relating the coefficients of APMA signal and odd order time-varying cumulants are established

from which two direct algorithms are presented for estimating parameters of APMA signal.As a consequence

the closed-form recursive formulas of APMA coefficients are derived.Simulations are given to illustrate the performance of the presented methods.
