| Abstract: | An improved local projective noise reduction for nonlinear time series is introduced.The comparison between improved local projective method and wavelet analysis for the de-noised Lorenz signal is given.The experiment results show that the improved local projective method is effective for the noise reduction of nonlinear signals. |

| Keywords: | local projective method chaotic signal noise reduction |
