Patent ID: 8670821

Claim:
An electroencephalogram signal processing method, comprising: a recording step retrieving EEG signal components of a testee via a plurality of electrodes, wherein the EEG signal components serve as an input signal; a retrieving step filtering the input signal to obtain a predetermined frequency band signal via a filtering unit, and subtracting the predetermined frequency band signal from the input signal to obtain a difference signal via a subtraction unit; a removing step performing an independent component analysis operation between the difference signal and a separating matrix to obtain an analysis signal via an analysis unit, generating a separating pseudo inverse and an independent analysis signal according to the separating matrix and the analysis signal respectively via a correction unit, and performing a matrix operation between the separating pseudo inverse and the independent analysis signal to obtain a corrected signal; and a synthesizing step adding the corrected signal and the predetermined frequency band signal together to obtain an output signal via an addition unit.
