Abstract

In this paper we review several digital signal processing (DSP) algorithms recently proposed (or introduced) for coherent optical communication system. There include the digital equalization algorithms for chromatic dispersion (CD) compensation, polarization recovery, and polarization mode dispersion compensation (PMD), and DSP algorithms for carrier frequency offset estimation and carrier phase recovery. A novel distortion mitigation algorithm developed for coherent receiver using single-ended photodetection will also be discussed.
