Briefly, this article describes an algorithm for controlling the power and operating point of a satellite transponder in an FDM (frequency division multiplexing) communication system. The uplink attenuation for a given earth station is determined by comparing transmitted power levels and corresponding returned power levels. The transmitted power levels are adjusted to compensate for uplink attenuation. If all earth stations in the system are similarly controlled, the transponder operating point can be maintained in a linear range.
