Abstract :
Higher-order singular value decomposition (HOSVD) is usually required in R-dimensional ( R-D) harmonic retrieval, where R ≥ 3. In this letter, we devise an iteratively reweighted HOSVD technique, which is referred to as IR-HOSVD, for multi-dimensional frequency estimation in the presence of impulsive noise. The main idea is to minimize the lp-norm residual errors along all the R dimensions, where . After decomposition, standard subspace techniques can be applied for parameter estimation. Based on the numerical results, IR-HOSVD outperforms several state-of-the-art techniques in terms of root mean square frequency error for different impulsive noise models.
