Results in terms of the NoB indicator. The respective 3D histograms show the frequency of the number of correctly detected breakpoints when the SNR changes, here for signal “4”. For each SNR and a specific basis type, 5000 experiments were performed (50 bases times 100 noise realizations). An expected trend is pronounced that increasing value of SNR lowers the number of correctly detected breakpoints, independently of the choice of the basis. The worst results are obtained using non-orthogonal bases (B)
