Learning to exploit z-Spatial Diversity for Coherent Nonlinear Optical Fiber Communication
Sebastian Jung, Tim Uhlemann, Alexander Span +2
Higher-order solitons inherently possess a spatial periodicity along the propagation axis. The pulse expands and compresses in both, frequency and time domain. This property is exp…
Introducing -lifting for Learning Nonlinear Pulse Shaping in Coherent Optical Communication
Tim Uhlemann, Alexander Span, Sebastian Dörner +1
Pulse shaping for coherent optical fiber communication has been an active area of research for the past decade. Most of the early schemes are based on classic Nyquist pulse shaping…
Deep-learning Autoencoder for Coherent and Nonlinear Optical Communication
Tim Uhlemann, Sebastian Cammerer, Alexander Span +2
Motivated by the recent success of end-to-end training of communications in the wireless domain, we strive to adapt the end-to-end-learning idea from the wireless case (i.e., linea…
Successive Eigenvalue Removal for Multi-Soliton Spectral Amplitude Estimation
Alexander Span, Vahid Aref, Henning Buelow +1
Optical nonlinear Fourier transform-based communication systems require an accurate estimation of a signal's nonlinear spectrum, computed usually by piecewise approximation methods…
Time-Bandwidth Product Perspective for Multi-Soliton Phase Modulation
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…
Efficient Precoding Scheme for Dual-Polarization Multi-Soliton Spectral Amplitude Modulation
Alexander Span, Vahid Aref, Henning Buelow +1
Spectral amplitude modulation for dual-polarization multi-soliton transmission is considered. We show, that spectral amplitudes become highly correlated during propagation along a…
