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…
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…
Non-Uniformly Coupled LDPC Codes: Better Thresholds, Smaller Rate-loss, and Less Complexity
Laurent Schmalen, Vahid Aref, Fanny Jardel
We consider spatially coupled low-density parity-check codes with finite smoothing parameters. A finite smoothing parameter is important for designing practical codes that are deco…
