PhD in Information Theory @ IMT Nord Europe
Open PhD position in Information Theory @ IMT Nord Europe (Lille)

We have an open position for a PhD student on the research area of Information Theory at IMT Nord Europe, former IMT Lille Douai, in Lille.

The proposed project will be on efficient code design for finite-blocklength coordination, at the intersection betweenInformation Theory, Coding, Large deviations and Neyman-Pearson theory.

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
