The objective of the Systuf project is to define and implement a new multi-service ground-to-vehicle wideband communication system in order to improve the quality of tomorrow's urban guided transportations (tram, underground and subway networks). The ground-to-vehicle radio communication system will be based on the latest 4G-LTE technology. Simpulse's contribution to the project concerns the development of the PHY-layer design and signal processing algorithms of the new communication system.
