Identification accuracies of five cases with the proposed method with (13) for Case A and the color noise with pre-whitening, where 7% inaccuracy noise information is added. The accuracy (%) is a percent ratio between the correct samples and all of samples, where the correct sample refers to the situation where the estimated number of dipole sources is the same as the number of real sources. (a) 5% color noise, (b) 10% color noise, (c) 20% color noise. The CCs ρ12, ρ23, ρ34 and ρ45 are 0.42.
