Hiring! Hiring! MSc or PhD student

With Prof. René J. Landry, we are seeking a candidate to enroll in the MSc or the PhD program within ÉTS to work with us in LASSENA lab on the following topic:

Enhancing localization with integrated terrestrial and non-terrestrial networks

The problem of outdoor and indoor localization using the integrated terrestrial and non-terrestrial network (ITNTN) is a challenging research area that requires a comprehensive understanding of the heterogeneous components of the network. The proposed project aims to investigate the challenge of achieving centimeter-precision localization using the signals of both terrestrial and non-terrestrial networks, including components such as cellular networks, Wi-Fi, UAVs, HAPS, and LEO satellites.

The candidate will begin with a detailed literature review of the current state-of-the-art in outdoor and indoor localization techniques. The review will also cover the existing research on the ITNTN and its components. Subsequently, the candidate will examine the localization approaches that combine heterogeneous components of the ITNTN and evaluate their performances, in both urban and suburban areas. The methodology will include the use of advanced techniques such as cross-layer optimization, MIMO, and beamforming. The proposed research will be conducted using a combination of theoretical analysis, simulation, and experimentation. The experiments will be conducted in a controlled environment using an open network laboratory to emulate realistic wireless environments.

The expected outcome of the proposed research is a comprehensive understanding of the challenges of achieving centimeter-precision localization in outdoor and indoor environments using ITNTN. The research will also provide insights into the localization methods based on multiple and heterogeneous signal sources. Finally, the research will provide a set of guidelines for designing cross-layer mechanisms that can achieve centimeter-precision localization using ITNTN.
