| Abstract: | The fundamentals of independent component analysis （ICA） is elaborated. The FastICA algorithm is applied to eliminating the power interference of seismic signal, the absolute values of correlation coefficient of the output signals are compared. The simulation results show that compared with the traditional power interference eliminating techniques, the FastICA algorithm can be more effective in removing the power interference of micro-signals. |
