Abstract

We perform chromatic dispersion (CD) equalization in the frequency domain based on Modified Discrete Fourier Transform (MDFT) Filter Banks (FB) with a non trivial prototype filter. The equalization is done per subchannel with a single tap equalizer placed between the analysis and the synthesis filter banks. Our main contribution is to design and insert the equalizer such that the output is alias free. We compare the MDFT FB with per subchannel single tap alias free equalization with the so called overlap and discard frequency domain equalization, which is nothing else than a MDFT FB with a trivial prototype filter. Larger CD values are tolerated with our approach at the cost of slightly increased complexity.
