Blind Channel Equalization Using Vector-Quantized Variational Autoencoders

no code implementations22 Feb 2023 Jinxiang Song, Vincent Lauinger, Yibo Wu, Christian Häger, Jochen Schröder, Alexandre Graell i Amat, Laurent Schmalen, Henk Wymeersch

Furthermore, we show that for the linear channel, the proposed scheme exhibits better convergence properties than the \ac{MMSE}-based, the \ac{CMA}-based, and the \ac{VAE}-based equalizers in terms of both convergence speed and robustness to variations in training batch size and learning rate.

Spatial Signal Design for Positioning via End-to-End Learning

no code implementations26 Sep 2022 Steven Rivetti, Josè Miguel Mateos-Ramos, Yibo Wu, Jinxiang Song, Musa Furkan Keskin, Vijaya Yajnanarayana, Christian Häger, Henk Wymeersch

This letter considers the problem of end-to-end learning for joint optimization of transmitter precoding and receiver processing for mmWave downlink positioning.

Model-Based End-to-End Learning for WDM Systems With Transceiver Hardware Impairments

1 code implementation29 Nov 2021 Jinxiang Song, Christian Häger, Jochen Schröder, Alexandre Graell i Amat, Henk Wymeersch

Simulation results show that the reinforcement-learning-based algorithm achieves similar performance to the standard supervised end-to-end learning approach assuming perfect channel knowledge.

End-to-End Learning for Integrated Sensing and Communication

no code implementations3 Nov 2021 José Miguel Mateos-Ramos, Jinxiang Song, Yibo Wu, Christian Häger, Musa Furkan Keskin, Vijaya Yajnanarayana, Henk Wymeersch

The approach includes the proposal of the AE architecture, a novel ISAC loss function, and the training procedure.

End-to-end Autoencoder for Superchannel Transceivers with Hardware Impairment

no code implementations29 Mar 2021 Jinxiang Song, Christian Häger, Jochen Schröder, Alexandre Graell i Amat, Henk Wymeersch

We propose an end-to-end learning-based approach for superchannel systems impaired by non-ideal hardware component.

Benchmarking End-to-end Learning of MIMO Physical-Layer Communication

no code implementations19 May 2020 Jinxiang Song, Christian Häger, Jochen Schröder, Tim O'Shea, Henk Wymeersch

End-to-end data-driven machine learning (ML) of multiple-input multiple-output (MIMO) systems has been shown to have the potential of exceeding the performance of engineered MIMO transceivers, without any a priori knowledge of communication-theoretic principles.

Learning Physical-Layer Communication with Quantized Feedback

1 code implementation19 Apr 2019 Jinxiang Song, Bile Peng, Christian Häger, Henk Wymeersch, Anant Sahai

A novel quantization method is proposed, which exploits the specific properties of the feedback signal and is suitable for non-stationary signal distributions.
