Abstract :
The article proposes an approach to harmonic retrieval in mixed Gaussian and non-Gaussian ARMA noises. Under the assumption of asymmetrically distributed non-Gaussian noise, the approach consists of third-order cumulant-based AR modeling of the non-Gaussian ARMA noise, followed by filtering the noisy output data, followed by fourth-order cumulant-based harmonic retrieval. The effectiveness of this approach is demonstrated through standard simulation results
