提出了一种基于导频序列辅助DSP的泵浦抖动消除算法，并在双偏振64 QAM光相位共轭系统中进行了实验验证。由于SBS抑制，观察到4.2dB的SNR改善。
A pump dithering removal algorithm, based on pilot sequence-aided DSP, is proposed and experimentally validated in dual polarization 64 QAM optical phase conjugation system. A 4.2 dB SNR improvement was observed due to the SBS suppression.
