Does the Cross-Talk Between Nonlinear Modes Limit the Performance of NFDM Systems?
Vahid Aref, Son T. Le, Henning Buelow
We show a non-negligible cross-talk between nonlinear modes in Nonlinear Frequency-Division Multiplexed system when data is modulated over the nonlinear Fourier spectrum, both the…
Probabilistic Eigenvalue Shaping for Nonlinear Fourier Transform Transmission
Andreas Buchberger, Alexandre Graell i Amat, Vahid Aref +1
We consider a nonlinear Fourier transform (NFT)-based transmission scheme, where data is embedded into the imaginary part of the nonlinear discrete spectrum. Inspired by probabilis…
125 Gbps Pre-Compensated Nonlinear Frequency-Division Multiplexed Transmission
Son T. Le, Vahid Aref, Henning Buelow
Record-high data rate of 125 Gb/s and SE over 2 bits/s/Hz in burst-mode single-polarization NFDM transmissions were achieved over 976 km of SSMF with EDFA-only amplification by tra…
On Time-Bandwidth Product of Multi-Soliton Pulses
Alexander Span, Vahid Aref, Henning Buelow +1
Multi-soliton pulses are potential candidates for fiber optical transmission where the information is modulated and recovered in the so-called nonlinear Fourier domain. While this…
Wave-like Decoding of Tail-biting Spatially Coupled LDPC Codes Through Iterative Demapping
Sebastian Cammerer, Laurent Schmalen, Vahid Aref +1
For finite coupling lengths, terminated spatially coupled low-density parity-check (SC-LDPC) codes show a non-negligible rate-loss. In this paper, we investigate if this rate loss…
Design Aspects of Multi-Soliton Pulses for Optical Fiber Transmission
Vahid Aref, Zhenhua Dong, Henning Buelow
We explain how to optimize the nonlinear spectrum of multi-soliton pulses by considering the practical constraints of transmitter, receiver, and lumped-amplified link. The optimiza…
