Abstract

We study the problem of estimating signal parameters from a noisy data sequence containing superimposed damped sinusoids. We propose three novel methods by combining the reduced-rank Hankel approximation and the Matrix Pencil method. We demonstrate that two of the proposed methods significantly outperform both the original Matrix Pencil method and the modified Kumaresan-Tufts method, especially at low signal-to-noise ratio.
