DVB-S air interface over railroad satellite channel: performance and extensions

In this paper the performance of the DVB-S air interface over the Railroad Satellite Channel (RSC) at Ku-band is investigated. Due to the peculiar channel impairments that characterize the satellite channel in the railway environment, some extensions to the DVB-S air interface as defined in [1] are proposed and analyzed in order to test the resulting link quality. The final aim is the design of a specific radio link capable to provide high quality internet and digital TV services to users travelling on high speed trains. This work is currently supported as part of the FIFTH project (Fast Internet for Fast Trains Hosts) by the European Commission under IST Contract Nr. 2001-39097 [2].
