Abstract
A system and method for performing automatic uplink power control (AUPC), using interference cancellation, to compensate for signal attenuation in a satellite communication system in which uplink path attenuation, forward channel attenuation, or both are estimated at a hub station without requiring signal quality reports from a remote station, and without requiring a satellite beacon. Estimates of uplink path attenuation or forward channel attenuation are used by the hub station to control the output power of a transmitted signal, thereby compensating for the estimated attenuation.
