Wintersemester 2007

Train-to-Ground Radio Propagation Channel

The Intelligent Transportation Systems (ITS) program is a broad research program initiated by the American Departement of Transportation in 2004. It focuses on intelligent vehicles, intelligent infrastructure and the creation of an intelligent transportation system through integration with and between these two components. ITS encompass a broad range of wireless and wireline communications-based information and electronics technologies. When integrated into the transportation system's infrastructure, and in vehicles themselves, these technologies relieve congestion, improve safety and enhance productivity.
This major research direction, as well as the current elaboration of several standards considering mobility (IEEE 802.11p, IEEE 802.16e also known as WIMAX) illustrate the fact that wireless mobility is a key research topic for the next generations of communication systems. In this project we will focus on train-to-ground access, connecting the high-speed train to the ground infrastructure. The communication channel has some specific features[1][2], depending on the train speed, location (bridge, tunnel,...) and relative positions of the infrastructure access points.
During this semester project the student will develop a channel model adapted to the train-to-ground communication and investigate methods to estimate it.
