文章通过软件编程和调试, 完成了基于数字信号处理(DSP)的偏振模色散(PMD)补偿逻辑控制模块的软件设计。详细介绍了系统的工作流程、软件及硬件结构, 以及粒子群优化(PSO)算法模块在DSP系统中的应用, 最后介绍了将该DSP系统应用到二阶PMD自适应补偿系统中进行验证的情况, 结果表明, 作者设计的DSP逻辑控制模块对一阶及二阶PMD补偿效果很好。

In this paper, DSP-based logic control module software design for Polarization Mode Dispersion (PMD) compensation systems is implemented by software programming and debugging. The system workflow, software and hardware frame and the applications of PSO algorithm module in DSP systems are introduced in detail. Finally, the application of DSP system in the 2nd-order PMD adaptive compensation systems is verified, the result of which shows that the DSP logic control module produces a great compensations effect on the 1st-and 2nd-order PMD.
