We propose a novel carrier phase recovery algorithm based on constellation partitioning and maximum likelihood phase decision (MLPD) for square 16-ary quadrature amplitude modulation format in optical coherent transmission systems and verify its performance by PDM-16QAM simulation. Compared with classic carrier phase recovery algorithm like blind phase search algorithm, the simulation results show that the complexity of the proposed algorithm is much lower while the OSNR tolerance is very similar.
