TABLE 2.
The accuracy (in %) of identification by the IC method with the optimal penalty function C1 for (12) and C4 for (13). The EEG signals under the color noise with pre-whitening are used with source configuration of Case B (Fig. 1(b)): sinusoid sources with close frequency band (9.9 Hz, 10 Hz and 10.1 Hz). Three groups (ρ12, ρ23) are used, e.g., (0.5, 0.5), (0.5, 0.6) and (0.5, 0.7). ). In the simulations of (12), the noise information is accuracy. In the simulations of (13), two noise inaccuracy values are considered, e.g., κ = 1% and 7%. NL: Noise level.
