Abstract :
We investigate a technique to speed up the convergence of Jansson´s deconvolution method. The technique extends the work of Agard who applied an inverse filter to the correction term in Jansson´s iterative equation. Test cases include severely overlapped peaks having moderate and low signal-to-noise ratios. The results show significant reductions in the final estimate´s rms error.
