Présentation

Biography --------- Catherine Douillard is a Professor at the Electronics Department of IMT Atlantique. She received the engineering degree in telecommunications from the École Nationale Supérieure des Télécommunications de Bretagne, France, in 1988, the Ph.D. degree in electrical engineering from the University of Western Brittany, France, in 1992, and the accreditation to supervise research from the University of Southern Brittany, France, in 2004. Her teaching area is digital electronics, VLSI circuit design and digital transmissions (error correcting codes). She is a member of the Codes research team in the Lab-STICC laboratory and was in charge of the Interaction between Algorithms and Silicon (IAS) team until 2020. Her main research interests are forward error correction codes and iterative decoding, iterative detection, the efficient combination of high spectral efficiency modulation and coding schemes, diversity techniques and turbo processing for multi-carrier, multi-antenna and multiple access transmission systems. Between 2007 and 2012, she participated in DVB (Digital Video Broadcasting) Technical Modules for the definition of DVB-T2, DVB-NGH and DVB-RCS NG standards. She served as the chairperson of the "Coding, Constellations and Interleaving" task force for the DVB-NGH TM group from 2010 to 2012. In 2009, she received the SEE/IEEE Glavieux Award for her contribution to standards and related industrial impact. She also served as the technical program committee (co-)chair of ISTC (International Symposium on Topics in Coding) in 2010 and 2018 and as the general (co-)chair of ISTC 2016 and ISTC 2021 and she will serve as the general chair of ISTC 2023. On-going research projects -------------------------- ### [AI4CODE](https://ai4code.projects.labsticc.fr/): "AI-aided FEC code design & decoding", ANR project, 2021-2025 The aim of the ANR AI4CODE project is therefore to explore and assess how Machine Learning (ML) techniques can contribute to improvements in coding theory, techniques, and practice. The focus is placed on Forward Error Correction (FEC),and the project is built around four inter-related objectives: Objective #1: Explore how ML can contribute to improving the state of the art (SoA) in FEC decoding. Objective #2: Investigate how ML techniques can improve current knowledge and practice in FEC code design. Objective #3: Learn from the machine. Objective #4: Develop a general expertise and critical thinking on ML algorithms and their applications to coding theory and practice. In AI4CODE, we will lead the investigations on AI-based structured interleaver design for Turbo codes, considering both very short codes and very long codes for which different challenges arise. ### [Beyond5G](https://beyond5g.wp.imt.fr/): "Support for investment in strategic sectors for the resilience of our Economy" - 5G Telecommunications, French recovery plan, 2020-2024 France is currently involved in initiatives led by the Comité Stratégique de Filière (CSF) for Digital Infrastructure, whose main objectives are to organize the sector necessary for the development of a sovereign digital telecom "industry" and its applications in other user sectors ("verticals") such as health, transportation and production industries. The Beyond5G project is part of this approach. Its main objective is to propose technical solutions for the development of sovereign and secure 5G/post 5G networks. It articulates these solutions to the needs of the verticals in the context, on the one hand, of a sustained effort in R&D and, on the other hand, of a significant interfacing between R&D and verticals. This can be done through the platforms that will be set up with the resources made available by the partners of the project, or through the portability of functional blocks and services resulting from the project's work. ### [QCSP](https://qcsp.univ-ubs.fr/): "Quasi-Cyclic Short Packet", ANR project, 2019-2022 The aim of the ANR QCSP project is to contribute to the evolution of IoT networks by defining, implementing and testing a new coded modulation scheme dedicated to IoT networks. The “big bet” of the project is to work on the emergence of Non-Binary (NB) codes combined with a Cyclic Code Shift Keying (CCSK) modulation. This new coded modulation scheme, called CCSK-NB-code, can be easily implemented in a cost efficient way at the device side. CCSK-NB-code provides several advantages compared to state of the art waveforms: it offers self-synchronization and self-identification capabilities, and is able to operate at ultra-low Signal-to-Noise Ratios (SNR). Our contribution to QCSP is mainly related to the investigation of non-binary turbo codes optimized for CCSK modulation. Recent research projects ------------------------ ### [EPIC](https://epic-h2020.eu/): "Enabling Practical wIreless Tb/s communications with next generation channel Coding", H2020 project, 2017-2020 H2020 European project in collaboration with 7 industrial and academic partners. EPIC aims to develop a new generation of Forward Error Correction (FEC) codes to enable practical wireless Tb/s technology, corresponding to a 10x-100x throughput improvement over the SoA for beyond-5G (B5G) systems. Our contributions to EPIC are mainly related to new architecture-aware high-throughput turbo decoding algorithms and to the investigation of non-binary turbo codes. ### [FANTASTIC-5G](http://fantastic5g.com/): "Flexible Air iNTerfAce for Scalable service delivery wiThin wIreless Communication networks of the 5th Generation", H2020 project, 2015-2017 H2020 European project, stemming from the 5GPPP consortium with 16 industrial and academic partners and led by Alcatel-Lucent. FANTASTIC-5G aims at developping a new multi-service 5G Air Interface (AI) for below 6 GHz through a modular design. To allow the system to adapt to the anticipated heterogeneity, the pursued properties are: flexibility, scalability, versatility, efficiency, future-proofness. In this project, we have contributed to the enhancement of the LTE turbo code and to the proposal of non-binary turbo codes for the different 5G core services: eMBB, URLLC and mMTC. We also studied new efficient resource allocation techniques for NOMA (Non-Orthogonal Multiple Access) transmissions.
