In fast-than-Nyquist wavelength division multiplexing (FTN-WDM) systems, the severe shaping filtering introduces serious inter-symbol-interference, and the long-distance fiber optical transmission also leads to more complex link impairments. Traditional chromatic dispersion (CD) estimation algorithms face the problems of difficulty in balancing complexity and estimation accuracy, and sensitivity to polarization mode dispersion (PMD) impairments. Aiming at the problem of large CD estimation error when traditional CD estimation algorithm has large PMD damage, a PMD-tolerant CD estimation algorithm for FTN coherent optical transmission systems is proposed. The algorithm achieves coarse CD estimation by stacking training sequences insensitive to PMD damage, and completes finer CD estimation by using the consistency parameter of clock phase detection. 64GBaud PM-16QAM FTN-WDM simulation results show that when the acceleration factor is 0.85 accumulated CD is 15360ps/nm and the CD estimation error is 200ps/nm, the PMD tolerance is about 100ps, and the complexity and PMD tolerance are 0.24 and 2.5 times of the peak average power ratio (PAPR) blind CD estimation algorithm, respectively.
