Abstrakti

Estimating the parameters of damped modes is generally computationally cumbersome, especially in cases when the model order of the signal is not known a priori. In this work, we propose a computationally efficient grid-less sparse reconstruction technique based on the recent SURE estimator developed for sinusoidal signals, extending it as to also allow for damped modes. In contrast to other estimators the proposed method allows for a non-uniform sampling scheme, thus presenting superior performance in applications where uniform sampling is suboptimal, hence broadening the application range. The performance of the proposed method is illustrated using both simulated and real spectroscopic data, clearly showing the improved performance as compared to previous techniques.
