Resumo(s)
Multidimensional 'H NMR spectra of
hiomolecules dissolved in light water are contaminated
by an intense water artifact. Generalized eigenvalue
decomposition methods using congruent matrix pencils are
used to separate the water artefact from the protein spectra.
Due to the statistical separation process, however, noise is
introduced into the reconstructed spectra. Hence Kernel -
based denoising techniques are discussed lo obtain noise- and
artifact - free 2D NOESY NMR spectra of proteins.
