N2 - A modulation format transparent carrier phase recovery scheme is proposed and demonstrated via numerical simulation. In our scheme, a kurtosis-based dichotomy scheme is firstly used for coarse phase noise estimation in a decision-free manner, and the residual phase noise is mitigated using blind phase search (BPS) with a few test phases for fine estimation. For QPSK, 16QAM, and 64QAM signals, the proposed scheme outperforms decision-based BPS under small optical signal to noise ratio (OSNR) and linewidth scenarios. Meanwhile, the proposed scheme also can provide 0.5 dB OSNR sensitivity gain and 4.5 times linewidth tolerance improvement over the previous modulation transparent kurtosis-based carrier recovery scheme for 64QAM signal.
