For the nonstationary property of the mixed process
Fourier series polyspectra and scaled polyperiodograms are introduced.We propose a new method to estimate frequencies of quadratic coupled harmonics in multilicative noise with zero mean and ones of cubic coupled harmonics in multiplicative noise with non-zero mean.Cupled frequencies can be obtained only by single record data and additive stationary noise is restrained without assumption of noise color and distribution.Finally
