Distributed Transmission and Spatially Coupled Forward Error Correction in Regenerative Multipoint-to-Point Networks
Laurent Schmalen, Tobias A. Eriksson, Fred Buchali +2
We investigate the performance of coded modulation for multi-hop regenerative optical networks. We analyze options for computing decoder input LLRs, show reach increases by optimiz…
Performance Metrics for Communication Systems with Forward Error Correction
Laurent Schmalen
We revisit performance metrics for optical communication systems with FEC. We illustrate the concept of universality and discuss the most widespread performance thresholds. Finally…
Impact of Bit Allocation Strategies on Machine Learning Performance in Rate Limited Systems
Afsaneh Gharouni, Peter Rost, Andreas Maeder +1
Intelligent entities such as self-driving vehicles, with their data being processed by machine learning units (MLU), are developing into an intertwined part of networks. These unit…
Deep Learning for Communication over Dispersive Nonlinear Channels: Performance and Comparison with Classical Digital Signal Processing
Boris Karanov, Gabriele Liga, Vahid Aref +3
In this paper, we apply deep learning for communication over dispersive channels with power detection, as encountered in low-cost optical intensity modulation/direct detection (IM/…
Statistics of the Nonlinear Discrete Spectrum of a Noisy Pulse
Francisco Javier Garcia-Gomez, Vahid Aref
In the presence of additive Gaussian noise, the statistics of the nonlinear Fourier transform (NFT) of a pulse are not yet completely known in closed form. In this paper, we propos…
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…
