AN OVERVIEW OF THE HARMONIC RETRIEVAL IN NOISE

Liang Yingchang Zhang Xianda Li Yanda (Department of Automation, Tsinghua University, Beijing 100084)  
Recently, Higher-order statistics have become powerful tools in signal processing field and have been applicable in harmonic retrieval. This paper first analyses the existing correlation-based methods for harmonic retrieval; then summarizes the newly developed higher-order statistics-based approaches and pre-filtering-based methods with hybrid higher-order statistics for estimating parameters of harmonics in noise. It is shown that higher-order statistics-based approaches are superior to correlation based approaches in restraining colored noise and retrieving useful information of harmonics.
