中文摘要：

根据波分复用（Wavelength Division Multiplexing，WDM）系统多信道偏振模色散（Polarization Mode Dispersion，PMD）的最坏信道补偿方案，将粒子群优化（Particle Swarm Optimization，PS（））算法用于多信道的PMD补偿．在补偿最坏信道的同时，保障了其他信道的性能．并以两信道PMD补偿系统为例进行了数值模拟，得到了很好的补偿效果．

英文摘要：

Particle swarm optimization （PSO） algorithm was introduced into Polarization Mode Dispersion （PMD） compensation in Warelength Division Multiplexing （WDM） systems based on the strategy of compensating the worst channel and making the balance. The worst-performing channel is compensated and the performance of other channels is also improved at the same time. The numerical simulation in a twochannel system was carried out and the results show that the compensation scheme is feasible.
