A propos du centre ou de la direction fonctionnelle

The Inria centre at Université Côte d'Azur includes 42 research teams and 9 support services. The centre's staff (about 500 people) is made up of scientists of different nationalities, engineers, technicians and administrative staff. The teams are mainly located on the university campuses of Sophia Antipolis and Nice as well as Montpellier, in close collaboration with research and higher education laboratories and establishments (Université Côte d'Azur, CNRS, INRAE, INSERM ...), but also with the regiona economic players.

With a presence in the fields of computational neuroscience and biology, data science and modeling, software engineering and certification, as well as collaborative robotics, the Inria Centre at Université Côte d'Azur  is a major player in terms of scientific excellence through its results and collaborations at both European and international levels.

Contexte et atouts du poste

The Postdoctoral appointment is joint with two INRIA research centers, Centre Inria d'Université Côte d'Azur (Samir M. Perlaza) and Centre Inria de Lyon (Jean-Marie Gorce). The position can be developed in either of these centers within a national collaboration network that includes INSA de Rennes (Philippe Mary). 

This position is supported by the French National Agency for Research (ANR) via the project n°ANR-22-PEFT-0010 of the France 2030 program.

Mission confiée

The appointment is in the broad intersection of information theory, communication theory, and game theory. As part of the national programme France 2030, funded by the French Government, the objective of this position is to study the fundamental limits on the reliability and throughput of decentralized communications systems. The underlying assumption is that independent receivers might broadcast a signal that can be observed by all receivers and thus, used to enhance reliability, throughput, or a convex combination of both. More importantly, transmitters are assumed to use a final constellation and a limited number of channel uses (finite block-length regime). 

The research activity is taken over within a strong national cooperation formed around the larger project, namely the PEPR -- Future Networks. The postdoc will participate in national workshops and seminars which are regularly organized within this larger project. 

Principales activités

 The expected results are in the form of fundamental limits, which are essentially information theoretic results (mathematical theorems) on:

  • Characterizations of the achievable and unachievable tuples of information rates and probability of error decoding that can be achieved in a multiple access channel thanks to a broadcast signal (a few bits) observed by all transmitters. 
  • Designs of (short-length) signalling systems  in decentralized networks that achieve near optimal trade-offs between information rates and decoding error probability.
  • Desing of (short-length) codes, compatible with signaling systems, that approach near optimal trade-offs between information rates and decoding error probability with reasonable decoding complexity.

 

Avantages

  • Subsidized meals
  • Partial reimbursement of public transport costs
  • Leave: 7 weeks of annual leave + 10 extra days off due to RTT (statutory reduction in working hours) + possibility of exceptional leave (sick children, moving home, etc.)
  • Possibility of teleworking and flexible organization of working hours
  • Professional equipment available (videoconferencing, loan of computer equipment, etc.)
  • Social, cultural and sports events and activities
  • Access to vocational training
  • Contribution to mutual insurance (subject to conditions)
