摘要：
We propose a modified-Viterbi and Viterbi phase estimation(VVPE)carrier phase recovery scheme that shows an effective capability of reducing the frequent and accumulated cycle slips induced by inter-symbol interference(ISI)in a faster-than-Nyquist(FTN)optical coherent communications system.In a 28-Gbaud FTN polarizationdivision multiplexed quadrature phase-shift keying optical communication system,the comparison of the proposed modified-VVPE scheme and the conventional VVPE scheme is carried out.It is proved that the proposed modified-VVPE scheme can effectively overcome the challenge of ISI induced error carrier phase estimation,which leads to a better bit error ratio performance.
