Abstract :
This paper investigates the use of an enhancement technique to speed up the convergence of Jansson´s deconvolution method. It uses an inverse filter function applied to the correction term in Jansson´s iterative equation. Test cases include peaks that are severely overlapped and have moderate and low signal-to-noise ratios. The results show significant reductions in the final estimate´s rms error
