title: [Single visual-evoked potential estimation based on sparse decomposition].
abstract: Iterative weighted sparse decomposition is a method to determine the weight coefficients of the minimum l1 norm optimization in accord with the two-scale relationship of the white noise in the multiresolution wavelet structure and to gradually suppress the influence of the strong noises through an iteration operation. The single-trial Visual Evoked Potential(VEP) estimation results confirmed the effectiveness of the method, and thus supported the viewpoint that the results of the single VEP estimation were different.
