Master 2 student or Engineer in the domain of wireless communications and radio propagation

Radio channel models for Railway environments using Ray Tracing tool

Location: Ifsttar, Cosys department, Villeneuve d’Ascq (F-59650)

                     6 months internship, starting date: 01/02/2018

Tutors: Dr Marion Berbineau (Ifsttar), Dr Yann Cocheril (Ifsttar)


Context and Objectives

In the context of the North Europe Region Smarties project from ELSAT 2020 program some research works are focusing on the development of adaptable wireless communications resilient to technology evolutions and to interferences able to answer the railway needs. In this context, in order to evaluate the new wireless system performance, we need to develop some radio channel models of the Railway environments.

In this internship we will consider mainly metro tunnel environments.

The objectives of the internship will be to model the physical structure of the considered tunnels and to simulate the radio propagation inside these tunnels using an available Ray Tracing based software. The arch-shaped tunnels are usually modelled using plane facets and we want first to compare the results with a previous study considering another methodology.

Experimental results from previous trials in real tunnels are available and will be used for comparison with the simulations.

After this first step, the aim is finally to characterize the radio channel in terms of time and frequency responses in order to define the relevant parameters that should be considered for future measurements in real tunnels in the 5.8 GHz band and also in the 60 GHz band.

Main skills: Wireless communications, radio propagation, channel models, informatics, mathematics, Matlab, very good level of English, writing, knowledge of Railway domain will be a plus.

Kow-how: Autonomy, sense of initiative, excellent relationship, rigor, taste for experiments.
