Abstract
Currently there is a clear trend towards vehicular satellite systems, which are designed in high frequency bands (Ku/Ka) and support broadband data services. One such system is designed within the European project MOWGLY for broadband services provision within aeronautical, maritime and railroad environments, and which features suitably adapted DVB-S2 and DVB-RCS standards as the basic underlying communications technology. This paper presents simulation results for assessing various aspects of the performance of the DVB-S2/RCS based satellite system in different mobile environments. In particular the effects of different fading mechanisms on the Block Error Rate performance of the system is analyzed through link-level simulations. Additionally, system-level simulation results are provided that apart from complementing the link level simulations include the modeling of propagation impairments such as path loss and rain attenuation that cannot be captured in link level simulations.
