First printing of this seminal paper within satellite cryptography. ""Perhaps the most significant research result involving the role of coding in satellite communications is the resource-sharing concept proposed by Acampora [the present paper]. As already mentioned, rain attenuation seriously impairs communications satellites operating at frequencies above 10 Ghz. Rather than using larger antennas or site diversity to minimize communication outage, a common pool of resources, shared among all ground stations, is much more efficient.""
