Maximum Likelihood Sequence Estimation for Chromatic Dispersion and Polarization Mode Dispersion Compensation in 3-Chip DPSK Modulation Format

We show that maximum-likelihood-sequence estimation (MLSE) of 10-Gbit/s 3-chip DPSK exhibits 1.6 dB penalty bound for 100-ps DGD and the CD tolerance 1.5 times of that of MLSE-equalized 10-Gbit/s 2-chip DPSK.
