Multiple Access, Time-Division Multiplex, Satellite Communications System.

Abstract

This document describes a multiple-access, time-division multiplex, satellite communications system in which the uplink and downlink frequencies are the same. In each ground station, the outgoing information (be it data, encoded data or digitized samples of the voice frequency signals) are assembled into a sequence of pulses to be transmitted as a burst in the time slot assigned to that particular earth station. If there are n ground stations in the system, n > or = 2, then the duration of each ground station sequence is, on the average, 1/2n times the duration of a complete frame or epoch, because for half of the epoch the satellite is in the receiving mode and the other half of the epoch the satellite is in the transmitting mode.
