Abstract :

Many problems exist in nature in which experimental data can be accurately modeled by a sum of damped exponential functions with real decay rates. Several methods have been reported for estimating such data. In this paper, matrix pencil method is used to postprocess the deconvolved data resulting from the application of modified Gardner transform to the transient multiexponential data signal. Processing of such data using other parametric methods has been previously reported. Although the results are not very good, the approach is promising as further modifications on it are expected to improve on the results. The problem of nonstationarity of the deconvolved data persists.
