Abstract
This work considers the semi-parametric estimation of sparse spec-

troscopic signals, aiming to form a detailed spectral representation

of both the frequency content and the spectral line widths of the oc-

curring signals. Extending on the recent FOCUSS-based SLIM al-

gorithm, we propose an alternative prior for a Bayesian formulation

of this sparse reconstruction method, exploiting a proposed suitable

prior for the noise variance. Examining three common models for

spectroscopic signals, the introduced technique allows for reliable

estimation of the characteristics of these models. Numerical sim-

ulations illustrate the improved performance of the proposed... (More)
