Abstract
A new harmonic retrieval approach that is highly tolerant to colored non-Gaussian noise is proposed. A fourth-order moment is used to estimate the noise AR polynomial in the noisy observations, then the harmonics can be retrieved via the filtered observations. The assumptions made in the reported studies, that the non-Gaussian noise is asymmetrically distributed and no quadratic phase coupling occurs, are released
