Concept and Experimental Demonstration of Optical IM/DD End-to-End System Optimization using a Generative Model
Boris Karanov, Mathieu Chagnon, Vahid Aref +3
We perform an experimental end-to-end transceiver optimization via deep learning using a generative adversarial network to approximate the test-bed channel. Previously, optimizatio…
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/…
Spatially Coupled LDPC Codes with Non-uniform Coupling for Improved Decoding Speed
Laurent Schmalen, Vahid Aref
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…
Dual-polarisation Non-linear Frequency-division Multiplexed Transmission with b-Modulation
Xianhe Yangzhang, Vahid Aref, Son Thai Le +3
There has been much interest in the non-linear frequency-division multiplexing (NFDM) transmission scheme in the optical fibre communication system. Up to date, most of the demonst…
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…
