摘要 相干光检测具有高灵敏度、高谱效率的优点,数字信号处理(DSP)技术能补偿任何形式的光纤传输损伤并实现信号光和本振光的载波同步,这两种技术的结合是下一代光纤系统发展的一个重要方向。主要介绍相干光通信系统中一些常见的DSP算法,并分析了各算法的优缺点。 Coherent detection has the advantages of high sensitivity and high spectral efficiency.Digital signal processing(DSP) technology can compensate any type of fiber impairments and can implement the carrier synchronization between received signal and the local oscillator as well.It will be a significant advancement to combine these two technologies for the next-generation optical fiber systems.In this paper,we introduce some prevalent DSP algorithms,and analyze their merits and drawbacks.
