Journal ArticleDOI
DSP for Coherent Single-Carrier Receivers
Maxim Kuschnerov,Fabian N. Hauske,K. Piyawanno,Bernhard Spinnler,M. S. Alfiad,Antonio Napoli,Berthold Lankl +6 more
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.
Journal ArticleDOI
Equalizer Design and Complexity for Digital Coherent Receivers
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.
Journal ArticleDOI
Optical Performance Monitoring in Digital Coherent Receivers
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.
Journal ArticleDOI
Spectrally Efficient Compatible Single-Sideband Modulation for OFDM Transmission With Direct Detection
Matthias Schuster,Sebastian Randel,Christian-Alexander Bunge,S.C.J. Lee,F. Breyer,Bernhard Spinnler,Klaus Petermann +6 more
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.
Journal ArticleDOI
Data-Aided Versus Blind Single-Carrier Coherent Receivers
Maxim Kuschnerov,M. Chouayakh,K. Piyawanno,Bernhard Spinnler,E. de Man,Peter Kainzmaier,M. S. Alfiad,Antonio Napoli,Berthold Lankl +8 more
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.
