RESPONSIBILITIES OF THE CANDIDATE: This 6 months work will concern the implementation in real-time of digital signal processing algorithms on a navigation platform. The main objective of this professional training is to compare the performances of the digital processing design in simulation (Matlab/Simulink) and in real-time on the GEDEX navigation platform. The trainee student should do a thorough bibliographical study on the GEDEX navigation platform and on the digital signal processing already developed. He will continue with a thorough analyze of the available real-time implementation procedures, specific to the GEDEX application.
