Nonlinear Fourier transform for optical data processing and transmission: advances and perspectives
Sergei K. Turitsyn,Jaroslaw E. Prilepsky,Son Thai Le,Sander Wahls,Leonid L. Frumin,Morteza Kamalian,Stanislav A. Derevyanko +6 more
TL;DR: The nonlinear Fourier transform is a transmission and signal processing technique that makes positive use of the Kerr nonlinearity in optical fibre channels.

Volker Jungnickel,Lars Thiele,Thomas Wirth,Thomas Haustein,S. Schiffermuller,Andreas Forck,Sander Wahls,Stephan Jaeckel,S. Schubert,H. Gabler,Christoph Juchems,F. Luhn,R. Zavrtak,Heinz Droste,G. Kadel,Wolfgang Kreher,J. Mueller,W. Stoermer,G. Wannemacher +18 more
TL;DR: A distributed CoMP transmission approach is implemented and tested in the downlink of an LTE-Advanced trial system operating in real time over 20 MHz bandwidth, with benefits over multi-cell channels recorded in an urban macro-cell scenario.
Journal ArticleDOI
Fast Numerical Nonlinear Fourier Transforms
Sander Wahls,H. Vincent Poor +1 more
TL;DR: Two fast numerical methods for computing the nonlinear Fourier transform with respect to the NSE are presented and achieves a runtime of O(D2) floating point operations, where D is the number of sample points.

Fast Numerical Nonlinear Fourier Transforms
Sander Wahls,H. Vincent Poor +1 more
TL;DR: In this article, two fast numerical methods for computing the nonlinear Fourier transform with respect to the Schrodinger equation (NSE) are presented, which achieves a runtime of O(D 2 ) floating point operations, where D is the number of sample points.
Journal ArticleDOI
FNFT: A Software Library for Computing Nonlinear Fourier Transforms
TL;DR: Nonlinear Fourier transforms (NFTs) are generalizations of the conventional Fourier transform that can be used to solve certain nonlinear evolution equations in a similar way.
