摘　　要：提出了一种应用于WDM系统中的自适应偏振模色散(PMD)补偿方法,用粒子群优化(PSO)算法来实现DOP的搜索和跟踪,并经D／A转换,将对应的电压施加在偏振控制器上,调制电压范围为0～10V,调节信号的基本偏振态,从而形成闭环反馈控制模块,通过多次迭代,得到DOP的最佳值,实现对PMD的自适应补偿。An adaptive PMD compensation method used in WDM system is proposed) in which the searching and tracking of DOP is achieved by particle swarm optimum (PSO) algorithm. After the D/A conversion, the voltages ranging from 0 to 10 V are performed on the polarization controller to adjust the basic polarization state of signal. Thus, a close-loop feedback control module can be built up, and through several iteration, the optimum of DOP is obtained and the adaptive PMD compensation is achieved.
