Multiple-Access Tradeoff Study for Intra-South American Satellite Communication System

This paper concerns two important aspects of a multiple-access tradeoff study for an intra-South American satellite communication system: 1) the radio-frequency transmitter power in both the satellite and the earth stations (particularly the former which is at a preminm) needing to give acceptable telephone channel signal-to-noise ratio performance; 2) the bandwidth requirements in both the satellite and the earth stations in relation to the traffic capacity to be accommodated, i.e., the comparative economy in the use of the radio-frequency spectrum.
