Abstract: In this letter, we propose a quasi-quadrature phase shift keying (QPSK) partitioning to replace the conventional QPSK partitioning in the first stage of the carrier phase estimation (CPE) algorithms for 32-QAM optical systems. By using the proposed quasi-QPSK-partitioning method, the ability of the CPE algorithms to track changes of phase is greatly enhanced. For 1-dB SNR penalty at bit error rate of 1E-2, the proposed method can achieve an improvement of 85% in combined linewidth symbol duration product tolerance when compared with the conventional method for single stage. With the help of the fine estimation stages, the maximum tolerable combined linewidth symbol duration product can be up to 5.1E-5.
