A preliminary investigation of a recursive asymmetrical adaptive filter for correcting asymmetrical distortions

Abstract

The author develops the LMS algorithm for a recursive asymmetrical equalizer. By expressing the terms needed to update the equalizer coefficients in the Z-transform domain, he shows that a common recursive filter structure may be used both for the equalizer and to generate the terms needed to update the coefficients of the equalizer. Simulation confirms the algorithm and the implementation.<>
