摘要：

For the parameter estimation of damped sinusoids, the linear prediction (LP) was recently applied to a forward-backward expanded-data matrix by Kannan and Kundu [Estimating parameters in the damped exponential model, Signal Processing 81 (2001) 2343-2351]. This version of LP will be called the expanded linear prediction (ELP). A key claim of that paper is that ELP offers a comparable performance as LP. The purpose of this letter is to prove that this claim does not hold true particularly for weakly damped sinusoids. (C) 2008 Elsevier B.V. All rights reserved.
