摘要：
This paper describes a method of estimating the parameters of sinusoidal harmonic signals buried in hybrid colored noise. We define novel high-order statistics-referred to as cross-fourth cumulant-that is the basic of the method proposed in this paper. The method is insensitive to hybrid colored noises. Employing cross-fourth-order cumulant, we estimated the sinusoid parameters using the moment method that has been developed on the Yule-walker equation of cross-fourth-order cumulant. Simulation results show that the new method is accurate and can suppress the effect of hybrid colored noise.
