In this paper we address the emerging application of mobility to DVB-S2/DVB-RCS systems, sometimes also referred to as Satellite-On-The Move (SOTM) communications. Satellite communications have great commercial success in digital audio and video broadcasting as they exploit the inherent wide area coverage for distribution content. It was a natural consequence to extend its use to multimedia applications; DVB-S2/DVB-RCS standards offer a commercially proven solution for fixed terminals in that sense. In addition, communication on the move is becoming a key market sector. Therefore broadband mobile communications represent an additional market for the satellite, addressing primarily transport operators (planes, ships, trains) but also end-users in cars. To ensure economies of scale and fast development and deployment of equipments, the adaptation of current satellite broadcast and interactive broadband standards is foreseen. This paper presents possible techniques applicable to different market segments for both the forward and the return links of the system, with associated performance and impact on the standards.

In this paper, the MoBISAT (Mobile Broadband Interactive Satellite Access Technology) system, the BcSAT (Broadband adaptive satellite communicationS and broadcAsting convergence Technology) system and the STC (Satellite and Terrestrial Convergence) system for interactive service on high speed train environment mainly deal with the information identified as system introduction, detail design description and implementation issues, respectively. First, MoBISAT system which represents a mobile broadband satellite access technology, provides satellite TV broadcasting service in Ku-band and high speed Internet service in Ka band based on DVB-S/DVB-RCS standard to the passengers and crews for land mobile, maritime and aeronautical environments (ETSI EN 301 790). BcSAT system aims at realizing the next generation satellite broadcasting service in Ka-band through DVB-S2 standard (ETSI EN 302 307). It can be implemented through high bandwidth-efficient and flexible transmission mode with provision of high order modulation scheme and robust channel coding technique. Furthermore, we're pursuing the development of prospective convergence system composed with satellite and terrestrial networks for realization of ubiquitous service, briefly. In a result, information of this paper will be useful to figure out the main design features and realistic consideration (IEEE Wireless Commun. 12(5) (2005), 91–97). [ABSTRACT FROM AUTHOR]
