Abstract
An adaptive transmitter power control for use in satellite communications systems wherein at least two ground stations communicate serial streams of binary data via a satellite transponder whose power-output is functionally dependent upon received signal strength. At least one of the ground stations includes a quality monitor which makes a real-time determination of the quality of the received signal, and generates signal quality indications in accordance with this determination. These signal quality indications are continuously communicated back to the corresponding transmitting station along with the serial stream of binary data. An encoder multiplexes the normal binary data and the signal quality indications into single, combined signal for transmission over only a single communications channel. The normal binary data and the signal quality indications are reconstructed at the transmitting station, where the signal quality indications are used to control the power level of the transmitted signal.
