A novel adaptive weighting scheme for background removal, applicable to both polynomial fitting and penalized least squares approaches, is proposed. Analysis of background fitting results for ensembles of simulated spectra, in comparison with three established methods, suggests that the method is robust and reliable and can significantly improve the background fit for spectra with structured backgrounds.
