[0028] Difficulties in extracting the EEG signs of the compound lower limb imagination movement: the cerebral cortex function area mapped by the lower limb movement is a relatively small area in the sulcus gyrus of the head, and its spatial structure is very limited, and the compound lower limb imagination movement involves multiple brain Functional areas and complex patterns further highlight the non-stationary characteristics of EEG signals. This leads to the limited applicability of traditional signal processing methods based on the hypothesis of short-term stability of EEG signals in the feature extraction of the EEG of the imaginary movements of the lower limbs. For this reason, the present invention aims at the non-stationary characteristics of EEG signals, and based on the conclusion that the event-related synchronization / desynchronization features of EEG are generated by the synchronous oscillation of group neurons, and proposes the application of empirical mode decompos...
