Abstract :
The coupled harmonics in multiplicative and additive noise is analyzed. We propose a slice polyspectra approach to identify cubic coupling harmonics. We also consider the problem of estimation of quadratic coupling harmonic frequencies in multiplicative and additive noise and propose a new method which obviates the assumption of multiplicative noise with nonzero mean in the existing method. Simulation examples illustrate the algorithms
