| 摘 要： | 针对标准粒子群优化(PSO)算法后期迭代效率不高和容易陷入局部极值问题,提出了一种基于变异机制的局部粒子群优化(VL-PSO,varied local particle swarm optimization)算法。在单信道100 Gbit/s光传输系统中,以VL-PSO算法作为逻辑控制算法,进行二阶偏振模色散(PMD)归零(RZ)码自适应补偿实验。结果表明,搜索补偿后,眼图张开度明显增大,平均搜索补偿时间为1.650 ms;并且VL-PSO算法能够实时跟踪补偿PMD的变化,跟踪时间小于0.431 ms。

| Abstract: | Because of low iterative efficiency and dropping into local optimum ea sily of the standard particle swarm optimization (PSO) algorithm the varied local particle swarm optimization (VLPSO) is proposed based on variation mechanism.In 100Gbit/s optical transmission system,the second-order polarization mode dispersion (PMD) return-to-zero (RZ) coding adaptive compensation experiment is performed based on VLPSO algorithm for logic control.The results show that after searching compensation,the openin g of eye diagrams is enhanced obviously and the average searching compensation t ime is 1.650ms.The VLPSO algorith m can follow and compensate the small change of PMD,whose tracking comp ensation time is less than 0.431ms. |
