摘要

在介绍了非线性光纤传输和最优信道均衡方案之后,验证了最近提出的分析步长选择和缩放规则,以获得相当的全局模拟精度,以模拟精度较低的光脉冲在光纤中传播的分步傅里叶(SSF)模拟。系统研究了不同色散映射度的归零(RZ)和载波抑制归零(CSRZ)调制格式在数字后置补偿中的应用及其计算性能。

Computation step-size study in digital post-compensation of fiber optic communication systems
After an introduction to the nonlinear fiber transmission and an optimal channel equalization scheme, recently proposed analytical step-size selection and scaling rules was verified to achieve comparable global simulation accuracy for split-step Fourier (SSF) simulations of optical pulse propagation through fiber with low simulation accuracy. Its application to digital post-compensation and its computational performance was systematically studied for return to zero (RZ) and carrier suppressed return to zero (CSRZ) modulation formats with different inline dispersion map degrees.
