Research projects
On-going research project
AI4CODE: "AI-aided FEC code design & decoding", 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.
QCSP: "Quasi-Cyclic Short Packet", 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.
Past research projects
EPIC: "Enabling Practical wIreless Tb/s communications with next generation channel Coding", 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.
My 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: "Flexible Air iNTerfAce for Scalable service delivery wiThin wIreless Communication networks of the 5th Generation", 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, I 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. I also studed new efficient resource allocation techniques for NOMA (Non-Orthogonal Multiple Access) transmissions.
M3: Mobile Multi-Media, 2010-2013
French ANR (Agence Nationale de la Recherche) project in collaboration with 7 industrial and academic partners: Orange Labs, CNES, Alcatel-Lucent, Teamcast, Parrot, Mitsubishi Electric, and INSA-IETR. Mobile Multi-Media project addressed the cooperation of broadcast and broadband standards, likely to be used to deliver multi-media services, whatever the location, the type of receiver, and the mobility situation of the user. Telecom Bretagne was in charge of studies related to Forward Error-Correcting (FEC) coding and diversity techniques.

Eurêka/Celtic European project in collaboration with more than 30 industrial and academic partners, intended to develop the next generation broadcasting standards and their implementations for portable, mobile and handheld reception.
Turbo codes, signal space diversity and MIMO techniques were studied in the framework of the project and also proposed for standardization to the DVB-H technical module.

Eurêka/Eurostars European project in collaboration with two European SMEs, Teamcast (
B21C: Broadcast for the 21st Century, 2007-2009
Eurêka/Celtic European project in collaboration with more than 30 industrial and academic partners, intended to elaborate technical propositions for the future of European digital TV. A new generation hybrid turbo code (3D-Turbo Code) and a signal space diversity technique were studied in the framework of the project and then proposed for standardization.
BSDT: study of enhanced digital transmission techniques for Broadband Satellite Digital Transmissions, 2006-2009
Research contract European Space Agency/Newtec: Proposal of a coded modulation scheme based on a Continuous Phase Modulation (CPM), for satellite transmission. This scheme, called 4CPM, has been implemented in the Belgian company Newtec’s triple play service terminals, Sat3play. These terminals were successfully put onto market via several satellite operators, including SES Astra (Astra2Connect service).
