Mis à jour le

Since late 2013, I’m an associate professor at the Department of Electronics, Optronics and Signal (DEOS) of the Institut Supérieur de l’Aéronautique et de l’Espace (ISAE-SUPAERO), University of Toulouse. My research interests are in the field of digital communications and related signal processing techniques (e.g., estimation/detection, time-frequency analysis...).

From 2012 to 2013, I was a temporary assistant professor (ATER) at the École Nationale Supérieure d’Informatique et de Mathématiques Appliquées de Grenoble (ENSIMAG).

In 2012, I obtained my PhD in signal processing applied to wireless communications at Grenoble Images Paroles Signal Automatique (GIPSA-lab), University of Grenoble.

In 2009, I obtained my engineer degree (MSc.) from the École Nationale Superieure des Télécommunications de Bretagne (today known as IMT-Atlantique).

PhD thesis position : Synchronization and security techniques for faster-than-Nyquist signals

 Research activities

Topics :

  • “faster-than-Nyquist” transmission techniques (interference mitigation, synchronization...) ;
  • multicarrier modulations over mobile radio channels (pulse shapes optimization, equalization, radar processing...).

Applications : satellite broadcasting, aeronautical communications, terrestrial cellular and ad-hoc networks...

Illustration of the increase of the signaling rate beyond the Nyquist criterion. A sinc-shaped signal with constant bandwidth B is plotted in time and in frequency. Notice that intersymbol interference (ISI) appears when the density is greater than one.

 Teaching activities

Signal processing (with E. Chaumette and S. Bidon),

Supaero, 1st and 2nd year.

Elementary signal processing tools such as spectral analysis, filter design, random processes, estimation are introduced through practical work sessions (e.g., building an FM receiver, processing radar signals...).

Introduction to radio-communication (with R. Pascaud),

Supaero, 2nd year.

We present the building blocks of a radio transceiver, including antennas, radio-frequency electronics and fundamentals of digital communications (linear modulations over AWGN channels).

Cybersecurity and electronic warfare (with M. Benammar),

Supaero, 2nd year (elective unit).

Applications, network and physical layer security aspects are addressed. Several practical work sessions allow to dive into a wide variety of subjects.

Student research projects,

Supaero, 2nd year.

One or more projects are proposed each year in the field of signal processing for digital communications. They are usually related to ongoing research topics (e.g., blind synchronization algorithms for multicarrier signals...).

Digital communications,

Supaero, 3rd year.

Common tools of signal processing are reviewed and used in order to present bases of digital communications. Advanced aspects such as synchronization. Several practical work sessions are proposed along with SDR examples : simulation of a linear transmission over AWGN channel, Costas 1st order synchronization loop, Gardner 2nd order timing loop.

Transmission over frequency selective channels,

Research Master TAST,

Frequency selective channels are modeled and several fading mitigation techniques are presented : single-carrier equalization, CP-OFDM with single-tap per sub-channel equalization, DSSS... Practical work includes the simulation of a CP-OFDM system over a multipath channel.
