Method and device for phase recovery and communication system comprising such device
TL;DR: In this paper, a method and a device are provided for phase recovery of at least two channels comprising the steps of (i) a phase is estimated for each channel; (ii) the phase estimated of each channel is superimposed by a coupling factor with at least one other phase estimated.

On the mode-dependent loss compensation for mode-division multiplexed systems
Adriana Lobato,Filipe Ferreira,Johannes Rabe,Beril Inan,Susmita Adhikari,Maxim Kuschnerov,Antonio Napoli,Bernhard Spinnler,Berthold Lankl +8 more
TL;DR: Simulation results find that the combination of strong mode coupling and advanced detection schemes, such as maximum-likelihood (ML) detection can improve the system performance in the presence of MDL, however, the effectiveness of ML detection has to be traded off with its larger computational complexity compared to linear equalization such as minimum mean square error equalization.

Data-aided single-carrier coherent receivers
M. Kuschnerov,K. Piyawanno,Erik De Man,M. Chouayakh,Bernhard Spinnler,M. S. Alfiad,Antonio Napoli,Berthold Lankl +7 more
TL;DR: Data-aided algorithms for coherent optic receivers are discussed as an extension of existing non-data aided methods that presents a scalable approach with low implementation complexity and limited overhead for higher-order modulation formats.

FFE, DFE and MLSE equalizers in phase modulated transmission systems
M. S. Alfiad,D. van den Borne,M. Kuschnerov,Bernhard Spinnler,T. Wuth,Antonio Napoli,Sander L. Jansen,H. de Waardt +7 more
TL;DR: It is demonstrated that for data rates ges40-Gb/s, FFE allows for the most efficient equalization of linear transmission impairments.
