Coding for Satellite Communication
IEEE Journal on Selected Areas in Communications, 1987This paper discusses a number of coding techniques for future satellite communication; they include Reed-Solomon error decoding for message blocks, probabilistic decoding techniques for punctured convolutional codes, and planar Euclidean geometry difference set codes for random multiple access applications.

2022 27th Asia Pacific Conference on Communications (APCC), 2022
As we move from 5G to 6G networks satellites will play an increasingly key part in providing coverage and resilience. Here we outline the timescales and some of the issues facing satellites in the 6G world.

A DTN approach to satellite communications
IEEE Journal on Selected Areas in Communications, 2008Satellite communications pose serious challenges to transport layer performance, mainly because of long propagation delays (especially in geosynchronous systems) and the possi ble presence of random errors on the satellite link. Solutions that cope with these impairments usually rely upon either the adoption of enhanced versions of transport protocols,

Throughput of a satellite channel communication
Acta Informatica, 1985The throughput of a satellite channel communication is depending upon the link protocol. It is well known that the ''classical'' HDLC protocol is inadequate when applied to satellite links instead of short terrestrial links. Several modifications have been proposed to overcome this problem.

Satellite Communications in Japan
IEEE Transactions on Communications, 1972This paper describes recent research and development of satellite communication technology in Japan together with the future prospects. Newly developed earth station facilities for both commercial and experimental purposes are described first. New satellite communication systems, such as STAR, SMAX, TTT, SSB-PM, and SSRA, which originated and/or have ...

DTN for LEO Satellite Communications
2011Satellite communications are an interesting and promising application field for Delay/Disruption Tolerant Networking (DTN). Although primarily conceived for deep space communications and sensor networks, it was immediately recognized that DTN was applicable to satellite environments, in particular to cope with the intermittent channels typical of LEO ...

Lunar communication satellites
Communications Satellite Systems Conference, 1966Abstract Exploration of the surface of the moon and successful operation of lunar bases in the 1970's and beyond will depend on reliable, long-range communication over the lunar globe as well as between the earth and moon. A system of communication satellites in lunar orbit can provide the communications needed over the moon's surface.
