Dynamic chromatic dispersion equalization in coherent optical fiber networks using least-mean-square algorithm. (arXiv:1606.04011v2 [cs.IT] UPDATED)
来源于:arXiv
In optical transport networks, signal lightpaths between two terminal nodes
can be different due to current network conditions. Thus the transmission
distance and accumulated dispersion in the lightpath cannot be predicted.
Therefore, the adaptive compensation of dynamic dispersion is necessary in such
networks to enable a flexible routing and switching. In this paper, we present
a detailed analysis on the adaptive dispersion compensation using the
least-mean-square (LMS) algorithms in coherent optical communication networks.
It is found that the variable-step-size LMS equalizer can achieve the same
performance with a lower complexity, compared to the traditional LMS algorithm. 查看全文>>
