In this work we describe a novel method for the combination of MRS signals acquired by a phased array coil taking into account possible noise correlations. Performance evaluation was carried out on simulated 1H-MRS signals and preliminary experimental results were obtained on phantom 1H-MR spectra. Our approach could be usefully applied in high density phased arrays, where it results from literature that noise correlations increase with the number of coil elements.
