The resulting T-F interdependence of the second simulated dataset. All results were estimated using a 0.5-s Hamming weighting window and a 0.75-s Hamming smoothing window. The second simulated dataset comparing three different T-F coherency estimators described by Equations (5), (9), and (11). Panels A, B, and C represent the magnitude of estimate T-F coherency in a single simulated signal pair using Equations (5), (9), and (11) respectively. Second and third rows (panels D–I) show the time and frequency-domain covariance matrices using Equations (17) and (18) at SN R = 0 dB. The bottom row represents the sensitivity, specificity, and z-scores in the interval of SN R∈[−30, 10] dB at 95% confidence interval for the three different methods estimated across 100 simulations.
