Efficient Training of Volterra Series-Based Pre-distortion Filter Using Neural Networks

no code implementations13 Dec 2021 Vinod Bajaj, Mathieu Chagnon, Sander Wahls, Vahid Aref

We present a simple, efficient "direct learning" approach to train Volterra series-based digital pre-distortion filters using neural networks.

End-to-End Learning of Joint Geometric and Probabilistic Constellation Shaping

no code implementations9 Dec 2021 Vahid Aref, Mathieu Chagnon

We present a novel autoencoder-based learning of joint geometric and probabilistic constellation shaping for coded-modulation systems.

On the Comparison of Single-Carrier vs. Digital Multi-Carrier Signaling for Long-Haul Transmission of Probabilistically Shaped Constellation Formats

no code implementations22 Sep 2021 Kaoutar Benyahya, Amirhossein Ghazisaeidi, Vahid Aref, Mathieu Chagnon, Aymeric Arnould, Stenio Ranzini, Haik Mardoyan, Fred Buchali, Jeremie Renaudier

Experimental Investigation of Deep Learning for Digital Signal Processing in Short Reach Optical Fiber Communications

no code implementations18 May 2020 Boris Karanov, Mathieu Chagnon, Vahid Aref, Filipe Ferreira, Domanic Lavery, Polina Bayvel, Laurent Schmalen

The investigation of digital signal processing (DSP) optimized on experimental data is extended to pulse amplitude modulation with receivers performing sliding window sequence estimation using a feed-forward or a recurrent neural network as well as classical nonlinear Volterra equalization.

Optical Fiber Communication Systems Based on End-to-End Deep Learning

no code implementations18 May 2020 Boris Karanov, Mathieu Chagnon, Vahid Aref, Domanic Lavery, Polina Bayvel, Laurent Schmalen

We investigate end-to-end optimized optical transmission systems based on feedforward or bidirectional recurrent neural networks (BRNN) and deep learning.

Concept and Experimental Demonstration of Optical IM/DD End-to-End System Optimization using a Generative Model

no code implementations11 Dec 2019 Boris Karanov, Mathieu Chagnon, Vahid Aref, Domaniç Lavery, Polina Bayvel, Laurent Schmalen

We perform an experimental end-to-end transceiver optimization via deep learning using a generative adversarial network to approximate the test-bed channel.

End-to-end Deep Learning of Optical Fiber Communications

no code implementations11 Apr 2018 Boris Karanov, Mathieu Chagnon, Félix Thouin, Tobias A. Eriksson, Henning Bülow, Domaniç Lavery, Polina Bayvel, Laurent Schmalen

In this paper, we implement an optical fiber communication system as an end-to-end deep neural network, including the complete chain of transmitter, channel model, and receiver.
