Analysis of Real Transient Multiexponential Signals Using Matrix Pencil Method in Labview Environment

Abstract

It has been a challenge for us to determine the most powerful and exact method for estimating parameters of a sum of real multi-exponentials signals. Indeed, in this study, we present and analyze two powerful methods for estimating these parameters. The first one is Matrix Pencil (MP) method, which is a linear technique for estimating the parameters. The second one is Pony method. In this work, we opted to reprogram the Matrix Pencil method and the Prony method in the Labview environment to automate signal processing and parameters estimation. The comparison between these methods shows that the Matrix Pencil method is more efficient in computation and faster. Simulation and experimental results indicate that Matrix Pencil method is less sensitive to noise than Prony method.
