Abstract
A received optical signal is coherently demodulated and converted into electrical complex samples (p(n); (px(n), py(n)), which are dispersion compensated in a compensation filter (). A control circuit () calculates comparison values (R, R) from corrected samples q(n) and an estimated error value (ε). A plurality of compensation function (T(M)) is applied according to a predetermined dispersion (CD) range and after a second iteration is the compensation filter () set to an optimum compensation function (T(M)).
