Abstract

A fast and low-complexity adaptive chromatic dispersion (CD) compensation algorithm based on delay-tap sampling technique for optical coherent systems is proposed. By generating a delay-tap plot from the signal powers after an adaptive CD equalizer, a parameter can be extracted from the delay-tap plot which can be used to estimate CD accurately. Simulation results for coherent polarization-division-multiplexed (PDM) quaternary phase-shift keying (QPSK) as well as 16-quadrature amplitude modulation (QAM) systems with various pulse shapes demonstrate that high CD estimation accuracies using relatively few data symbols can be achieved in presence of other transmission impairments.
