    • Abstract
  • Using the wavelet package analysis,the better localization property is possessed simultaneously in time domain and frequency domain.After the wavelet package transform of signal is conducted,the space movement property of particle is calculated by spectral matrix method,constituting the corresponding filtered function.The decomposed signal is filtered,the filtered results are reconstituted by reverse wavelet package transform.The objectives of filtering the interference and reserving the effective signal are realized,obtaining the satisfactory effectiveness.
