1Joint High-Resolution Fundamental Frequency and Order Estimation

Abstract — In this paper, we present a novel method for joint estimation of the fundamental frequency and order of a set of harmonically related sinusoids based on the MUSIC estimation criterion. The presented method, termed HMUSIC, is shown to have an efficient implementation using FFTs. Furthermore, refined estimates can be obtained using a gradient-based method. Illustrative examples of the application of the algorithm to real-life speech and audio signals are given, and the statistical performance of the estimator is evaluated using synthetic signals, demonstrating its good statistical properties.
