30 minutes from Bruxelles)

 

Summary:

Ensuring cooperation of autonomous devices in a decentralized network is an ambitious objective that

compels us to go beyond the traditional problem of reliable communications. We propose to use the

notion of coordination , which is intended as a way of enforcing a prescribed joint behavior of the

devices through communication, by synthesizing joint distributions which approximate a target behavior

of the agents. With this project, we intend to move one step closer to real-life applications by looking at

the short block-length regime. Moreover, this PhD thesis will tackle two complementary aspects of

coordination with short packets. First, we will have to design efficient coding schemes which are

consistent with the known capacity bounds for the coordination region in the short block-length setting.

At the same time, given the lack of results on finite-length coordination, we aim at better understanding

the nature of the coordination problem by deriving new bounds for multi-user network settings.

 

Objectives:

Within this PhD, we intent to focus on the following objectives:

Objective 1: Design of coordination coding schemes

Objective 2: Derivation of new coordination rate regions for multi-nodes networks

 

Additional information:

The successful candidate will be a member of the Digital System group of IMT Lille Douai (website:

http://imt-lille-douai.fr/en/about-us/identity/). IMT Lille Douai is located in Villeneuve d’Ascq, at

approximately 1h30 by TGV train from center Paris.

 

The successful candidate can start as soon as possible.

 

Applications are sought from France, EU and international candidates with an outstanding academic

background, especially in information theory, channel coding or related disciplines. Demonstrable

mathematical skills will be essential. The candidate should be familiar with key engineering

programming languages (Matlab, Python, …)

Applicants must have an Msc degree (M2, engineer degree or equivalent in France). A good and

working knowledge of the English Language is required.
