Introduction of Mobility Aspects for DVB-S2/RCS Broadband Systems

Abstract

In this paper we address the emerging application of mobility to DVB-RCS systems.

Railway satellite channel at Ku band and above: Composite dynamic modeling for the design of fade mitigation techniques

“…From a standardization point of view, the respective system specifications commonly rely on the digital video broadcasting via satellite second-generation/return channel via satellite (DVB-S2/RCS2) pair of standards [1,2], in the fixed case, and on the digital video broadcasting satellite to handheld (DVB-SH) standard [3], in the mobile case. However, in recent years, the boundary between these two typical system categories is becoming vague because there are efforts for introducing mobility into DVB-S2-based systems in the frame of vehicular, maritime, aeronautical and railway scenarios [4][5][6]. The latter references also include a long listing of relevant ESA ARTES (European Space Agency Advanced Research in Telecommunications Systems), European Space Agency Advanced Research in Telecommunications Systems (ESA ARTES), European Union Information Society Technologies (EU IST), Electronics and Telecommunications Research Institute (ETRI ) and industrial programs as well as pre-commercial trial/fully commercial activities.…”

“…, the log normal statistical parameters {m M , s M } in the mobile case are related through Eqn(6) with {m F , s F } of the corresponding fixed log normal distribution, and erfc(.) is the complementary error function 2.…”

Admission control and handover management for high‐speed trains in vehicular geostationary satellite networks with terrestrial gap‐filling

“…Recently, both EU and ESA have sponsored R&D programmes to introduce mobility capabilities to DVB-RCS in order to provide broadband satellite services to collective mobile communities such as passengers of airlines, maritime vessels and high-speed trains [17][18][19]. In particular, high-speed trains are expected to be one of the major communities that will exploit broadband satellite services, even if they have posed special challenges due to the peculiar characteristics of the railroad satellite channel [20].…”
