Abstract
A system for transmitting and receiving outbound and inbound data signals through a satellite communications network, the system having a network data rate and including a satellite and an end user transceiver, the system comprising a half-duplex mobile transceiver for transmitting and receiving the inbound and outbound data signals, respectively, for spreading the inbound data signal from the network data rate to a reduced data rate having an increased signal-to-noise ratio using a spread sequence, and for despreading the outbound data signal from the reduced data rate to the network data rate. The system also comprises an earth station, coupled to the end user transceiver, for transmitting and receiving the outbound and inbound data signals, wherein the earth station includes means for spreading the outbound data signal from the network data rate to the reduced data rate using the spread sequence, and means for despreading the inbound data signal from the reduced data rate to the network data rate, and wherein the end-user transceiver includes means for transmitting the outbound data signal and for receiving the inbound data signal.
