Abstract
The present invention discloses an apparatus for use by a coherent receiver, comprising means for: obtaining a first set of coefficients (A+ ) indicating a first adaptive filter (A) configured to reduce at least part of polarization mode dispersion in an equalizer of the coherent receiver and a second set of coefficients (w+ ) indicating a second adaptive filter (w) configured to reduce at least part of the inter-symbol interference in the equalizer of the coherent receiver, determining a first updated set of coefficients (A++ ) and a second updated set of coefficients (w++ ) based on the first set of coefficients (A+ ) and the second set of coefficients (w+ ), wherein the gains of the first updated set of coefficients (A++ ) have a predetermined level, and wherein, the output of the equalizer based on the first set of coefficients (A+ ) and the second set of coefficients (w+ ) is approximately same as the output of the equalizer based on the first updated set of coefficients (A++ ) and the second updated set of coefficients (w++ ), providing the first updated set of coefficients (A++ ) and the second updated set of coefficients (w++ ) to the first filter and the second filter respectively.
