Associate professor at the institut supérieur de l’aéronautique et de l’espace (ISAE-Supaero), member of electronics, optronics and signal department (DEOS). My research takes place in the signal, communication, antennas and navigation (SCAN) team.

Ph.D. in signal processing and telecommunications (Université de Grenoble, 2012), qualified in 61th section. Engineer in telecommunications and networks (TELECOM Bretagne, 2009).

 Research activities

My research topics are mainly in the field of high throughput secured communications. In particular :

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

Various applications are targeted : satellite broadcasting, 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 Y. Bachy),
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...).
Review of signal processing tools,
Specialized Master TERA.
Basic tools of signal processing are reviewed through a project-based learning (PBL) approach (e.g., complex representations of bandpass signals, sampling and reconstruction techniques, spectral analysis, filtering...). An FM receiver is built with Matlab and assessed with captured 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,
Specialized Master TERA and 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.
Aeronautical communications,
Specialized Master TERA and Research Master TAST
Signal processing aspects of aeronautical communications are developed. It includes mobile radio channel modeling in VHF/UHF bands, analog voice modulations (amplitude, frequency), digital transmission systems (ACARS, VDL 2). A real voice transmission system is finally built thanks to SDR transceivers.

 Projects

The RAdio Logicielle pour la Formation (RALF) project has been co-funded by the University of Toulouse (IDEX Toulouse Ingénierie 2014) and ISAE-Supaero in order to promote software defined radio techniques in several engineering trainings. It enables to bridge the gap between theory and practice in various signal processing courses...
The grant from the University of Toulouse IDEX Nouveaux Entrants is intended to help researchers and professors newly arrived in Toulouse. The grant can be used to facilitate national and international cooperation, buy equipments... Duration : 2014-2017.
