| 摘 要： | 研究了两段PMD补偿器和补偿算法.存在二阶效应时,PMD补偿中的反馈信号将是一个多峰多谷的复杂信号.粒子群算法(PSO )作为一种优化算法已在实验中实现.研究了模拟退火算法（SA）作为含二阶PMD补偿的反馈信号的应用.通过仿真计算还比较了采用这两种算法的PMD补偿性能.

| Abstract: | The two-stage 2-order PMDC has been investigated and the 2-order compensation scheme has also been proposed.Feedback signals are multiple peaks and multiple valleys function with the controlled parameters of PMDC considering the 2-order PMD.As a combination optimization algorithm,PSO has been presented and demonstrated in experiment.SA as the optimization algorithms in PMD compensation up to 2-order have been researched.Comparisons of PSO and SA were presented in detailed in simulation. |
