A Robust and Computationally Efficient Subspace-Based Fundamental Frequency Estimator

Abstract

This paper presents a method for high-resolution fundamental frequency (F 0) estimation based on subspaces decomposed from a frequency-selective data model, by effectively splitting the signal into a number of subbands. The resulting estimator is termed frequency-selective harmonic MUSIC (F-HMUSIC). The subband-based approach is expected to ensure… (More)
