Wang Jinghui, Liu Jianfei, Wang Mengjun, et al. Study on LMS algorithm-based adaptive equalizer for fiber channels[J]. 2010,(2):10-12. DOI: 10.13756/j.gtxyj.2010.02.007.
we analyze the main factors that affect the performances of fiber-optic communication systems
set up the simulation model of the single-mode fiber channels on the basis of theoretical analysis
introduce the basic structure of the Division Feedback Equalizer(DFE) and the LMS algorithm and imitate by using the MATLAB software the adaptive equalization performances of 10 Gbit/s fiber channels using the LMS algorithm.Simulation results indicate that the LMS algorithm is simple and efficient and can effectively eliminate the inter-symbol interference caused by fiber dispersion and Polarization Mode Dispersion(PMD)
appropriate for fiber-optic communication systems that require high equalization speed.
