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

  • 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
  • Social, cultural and sports events and activities
  • Access to vocational training
