Journal ArticleDOI
Integration of satellite and terrestrial systems in future multimedia communications
Barry G. Evans,Markus Werner,Erich Lutz,Michel Bousquet,Giovanni Emanuele Corazza,Gérard Maral,Robert Rumeau +6 more
TL;DR: The role of satellite communications in future telecommunication networks and service provision is examined, and future ways forward for satellites are outlined, and the research challenges and technology advances needed to facilitate this integrated approach are discussed.
Journal ArticleDOI
ATM-based routing in LEO/MEO satellite networks with intersatellite links
TL;DR: An asynchronous transfer mode (ATM)-based concept for the routing of information in a low Earth orbit/medium Earth orbit (LEO/MEO) satellite system including intersatellite links (ISLs) is proposed, with specific emphasis on the design of an ATM-based routing scheme for the ISL part of the system.
Journal ArticleDOI
Low earth orbit satellite systems for communications
TL;DR: This paper heralds the coming of the new era with a tutorial approach to the system design and trade-offs of LEO constellation system design, which discusses orbital configurations, network topologies and routeing considerations, multiple access schemes and link performance design.
Journal ArticleDOI
Performance analysis for a guaranteed handover service in an LEO constellation with a "satellite-fixed cell" system
TL;DR: This paper proposes a strategy which eliminates forced call terminations due to handover failures, thus allowing the GH service, and an analytical model has been derived to calculate QoS parameters for a mixed population of GH and regular users.
Patent
Digital filter-type frequency demultiplexing device
Xiao Yong Guo,Gérard Maral +1 more
TL;DR: In this paper, a polyphase network architecture is combined with a stage of delay lines for processing separate groups of multiplexed modulated carriers with identical bandwidth by programming a Fourier transform complex multiplying circuit.
