A New Windowing Method for the Parameter Estimation of Damped Sinusoids
Résumé
This paper presents a preprocessing technique based on exponential windowing (EW) for parameter
estimation of superimposed exponentially damped sinusoids. It is shown that the EW technique signifi-
cantly improves the robustness to noise over two other commonly used preprocessing techniques: subspace
decomposition and higher order statistics. An ad-hoc but efficient approach for the EW parameter selection
is provided and shown to provide close to CRB performance
