Research on the method of noise interference in brain information perception system

As an important hardware component in the process of EEG recognition, the brain information perception system undertakes the functions of accurate EEG signal acquisition, amplification, conversion, transmission and recognition. As the EEG signal shows the characteristics of weak in amplitude, low SNR, low frequency range and strong randomness, it can be easily affected by electromagnetic interference in the environment. Thus leads to a decrease in accuracy. Therefore, the interference sources that interfere with the brain information perception process are sorted out, the simulation is carried out for different objective factors, in order to explore the influence of electromagnetic interference in the environment on the brain information perception system. Finally, we provide reference and ideas for the interference of the brain information perception system.
