Sparse Estimation Of Spectroscopic Signals
(2011) 19th European Signal Processing Conference, EUSIPCO 2011 2011. p.333-337- 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) - This work considers the semi-parametric estimation of sparse spec-
