IMT Atlantique, internationally recognized for the quality of its research, is a leading general engineering school under the authority of the Ministry of Industry and Digital Technologies, ranked in the 3 main international rankings (THE, SHANGAI, QS). With three campuses in Brest, Nantes and Rennes, IMT Atlantique aims to combine digital technology and energy to transform society and industry through training, research and innovation.
Trains are entering the era of full automation thanks to wireless systems shifting control functions from the human driver to computers. High data rate, robustness, high reliability and ultra-low latency are required. The Future Railway Mobile Communication System (FRMCS) is under development at European level. The objective in considering mmW is to improve the communication system adaptability for full bearer independency. The 60 GHz band is of great interest for railway in case of very high data rate and very low latency requirements. The environment (ballast, cutting, tunnels, high voltage near the antennas, dust, interferences, etc.) as well as the constraints (vibrations of the trains, non-line of sight situations, crossing of trains, cohabitation with other systems, etc.) are very specific and will impact the performances of the wireless links for both Train-to-Infrastructure (T2I) and Train-to-Train (T2T). The propagation conditions and channel behaviour have to be well known to avoid communication outages particularly in the context of mobility. Dedicated channel models for mmW in railway environments are needed. This work is in the framework of a national research project: mmW4Rail in collaboration with the university Gustave Eiffel, Merce, the university of Haut de France.
A mmw channel sounder is currently designed in the research laboratory Lab-STICC/IMT Atlantique. The Post-doc will contribute to the evolution and improvement of this mmw channel sounder. The calibration is a critical part that could be proceed to measure geometrical channel impulse response. He/she will participate to the evolution of the mmw sounder, the calibration process. From measurement campaigns, he/she will process the data measurement to extract 3D channel responses.
PhD in in Electromagnetism, Radiofrequency, propagation.
