Abstract
AbstractThis paper evaluates the applicability of the DVB‐S2 standard in railway environments, where the most peculiar impairment is the periodic deep fading caused by power‐supply arches distributed along the rail tracks. This effect induces a link loss every time the train antenna undergoes a power arch and cannot be counteracted with transmission power. Therefore, we propose and investigate the use of antenna diversity on the train. Simulation and semi‐analytical results show that second‐order diversity suffices to remove the packet error floor observed in the case of a single receiving antenna, thus enabling the application of DVB‐S2 to this harsh environment.
