Abstract：The environmental noise and frequency noise interference on EEG for further processing and analysis with the extremely disadvantageous influence. In view of the traditional wavelet coefficients by soft threshold de noise processing method of waveform distortion and hard threshold de noise processing method after the oscillation phenomenon, put forward a new wavelet coefficients nonlinear continuous function attenuation processing algorithm. By means of the wavelet coefficients of the nonlinear attenuation process, the low values of a continuous function between the end of wavelet coefficients between hard and soft threshold, effectively avoid the waveform distortion and oscillation. Processed EEG signal to noise ratio and mean square error are superior to the traditional wavelet denoising processing method.
