Dispersion Compensation Schemes – A System Perspective

In this section, we will show how dispersion compensation schemes affect the system performance. The pulse broadening effect of chromatic dispersion causes the signals in the adjacent bit periods to overlap. This is called intersymbol interference (ISI). Broadening is a …
