TL;DR: This paper presents a new and fast algorithm to perform blind adaptive CD compensation through frequency-domain equalization and proposes an XPM-mitigating carrier phase recovery as an extension of the standard Viterbi-Viterbi algorithm.

TL;DR: An overview of digital equalization algorithms for coherent receivers and derive expressions for their complexity is given, which compare single-carrier and multicarrier approaches, and investigates blind equalizer adaptation as well as training-symbol-based algorithms.

TL;DR: In this paper, a method for combined fiber parameter estimation from digital filter coefficients of a polarization diverse coherent receiver is presented, where all deterministic linear optical channel parameters like residual chromatic dispersion (CD), polarization-mode dispersion, and polarization dependent loss (PDL) are continuously monitored by analysis of the filter impulse response of the adaptive equalizer.

TL;DR: A combination of orthogonal frequency-division multiplexing and compatible single-sideband modulation (CompSSB) using a standard direct-detection scheme is suggested to overcome chromatic dispersion without explicit compensation.

TL;DR: In this paper, blind and data-aided receivers are compared for coherent single-carrier optical systems in terms of complexity, tracking ability, and convergence speed for time-domain and frequency-domain-based receivers.
