Embodiment Construction
[0015] Such as figure 1 As shown, the raw data of 15 channels Fz, Pz, Oz, Fp1, Fp2, F7, F3, F4, F8, C3, C4, P7, P3, P4 and P8 are recorded by the gUSBamp amplifier.
[0016] The processing unit of EEG data is 1s, select the original EEG data x(n)={x(0),x(1),..., x(N-1)}, use the Welch method to estimate the power spectrum, select the Hanning window function w(n) for window processing, then calculate the power spectrum estimation of the M frequency band of the channel w:
[0017] I M ( w ) = 1 MU | Σ n = 0 M - 1 x ( n ) w ...
