Individual and combined spectra in the simulated scenario of intrinsic correlation noise with large difference on the variances: (a) individual spectra received on each of eight coil/channel elements, (b) combined spectra obtained by the proposed ${\mathit{R}}_N^{-1}\mathit{s}$ weighting method along with the S/N² weighting and equal weighting methods. The three methods produced a SNR of 70.25, 59.96, and 36.52, respectively.
