- W1948200432 abstract "在40 Gbit/s相干偏振复用正交相移键控（QPSK）传输系统中,为了补偿由于光纤中非线性效应引起的传输信号损伤,采用了基于Manakov方程的反向传播非线性补偿算法.传统的基于标量非线性薛定谔方程（NLSE）的反向传播算法忽略了偏振模色散（PMD）的作用,因此在偏振复用系统中不能补偿由于PMD引起的信号损伤|而基于Manakov方程的数字信号处理方法能够对PMD与克尔非线性效应的耦合作用进行补偿.从仿真与实验两个方面对此方法在40 Gbit/s相干偏振复用QPSK传输系统中的补偿效果进行了验证.结果均表明,与NLSE相比,基于Manakov方程的反向传播算法在400 km长距离QPSK传输中显示出更好的性能.在光信噪比（OSNR）为18 dB时,基于Manakov方程的反向传播算法得到的Q值与NLSE相比提高约3dB." @default.
