The paper not only studies the noise reduction methods of chaotic time series with noise and its reconstruction techniques, but also discusses prediction techniques of chaotic time series and its applications based on chaotic data noise reduction.
      


A new noise reduction method based on restrain of the physical properties of electromagnetic data is put forward. The basic criterion of this noise reduction method is to seek the physical rationality of the electromagnetic data after the noise reduction processing. Theoretical modeling results have shown this method is rational, reliable and practical means for EM data noise reduction. Combining this method with Forward Modifying Inversion method, the resistivity distribution and other geometric parameters...
