摘要：
The performances of the proposed decision-aided maximum likelihood (DA ML) and maximum likelihood sequence detection (MLSD) algorithms are investigated in this paper. It is shown that MLSD significantly improves laser linewidth tolerance. 100 Gb/s DP-QPSK experiments are carried out to verify our results.
