ABSTRACT:
An information transmission system includes a base station with a base transmitter and a plurality of satellite stations. Each satellite station includes a satellite receiver for receiving a transmission from the base station and a satellite transmitter including a transmitter amplifier, the transmitter amplifier requiring a preparation period of time to prepare the transmitter amplifier for operation. The transmission of information between and satellite station and the base station occurs during a transmission portion of a selected time slot within a succession of time slots. The amplifier in each of the satellite stations is prepared for transmission during a preparation portion of a same time slot having a duration at least equal to the preparation period for the satellite station transmitters and occurring prior to the transmission portion of the selected time slot. In another embodiment, information is transmitted from the base station during the selected time slot to a plurality of the satellite stations. The transmitters of each satellite station are prepared during a time slot prior to the selected time slot or are partially prepared both during a prior time slot and during the selected time slot, prior to the transmission in each time slot.
