Abstract: In practice, LPSVD is one of the most interesting linear-prediction techniques instead of FFT now. In this paper, a method is proposed by means of proportional exponential weighting which is performed after LPSVD, one can keep all characteristic parameters in HRNMR-spectra and improve their resolution, so far as a spectrum can be reconstructed by a group of lines with the same chemical shifts, intensities or integration of FFT spectra.

Key words: Proportional exponential weighting, LPSVD, Resolution
