BSS performance on MRS data versus the number of observations. Average results of blind separation of two simulated MRS metabolites. The SNR value is set to 10 dB. Left: the average error $\alpha \left({\left\{\mathit{s}\right[f\left]\right\}}^{\mathsf{\text{T}}},{\left\{\tilde{\mathit{s}}\right[f\left]\right\}}^{\mathsf{\text{T}}}\right)$ evolution of all the algorithms as a function of the number of observations. Right: the average numerical complexities (top) and the CPU time (bottom) of all the algorithms, respectively.
