  • Inversion of channel distortion by adaptive wavelet lifting
    Patent number: 8144803
    Abstract: A method for inverting telecommunication channel distortion by adaptive wavelet lifting. The distortion signal is analyzed using wavelet lifting and the inverse filter is computed. Coefficients of the inverse filter are used to either compute a transmission pre-filter or to update the transmitted message.
