摘要
An approach for optimizing power utilization of a satellite transponder, and thereby optimizing achievable modulation/coding schemes and data rates for terminals across the transponder beam, is provided. A signal power level is allocated to each of a plurality of carriers. The plurality of carriers are to be transmitted within a downlink beam via a transponder, each of the carriers is associated with a region of the beam, and the total power allocated to the carriers does not exceed a desired aggregate power level for the transponder. The signal power allocated to each carrier is determined relative to a gain realizable by satellite terminals within the respective beam region and assigned to receive the respective carrier, and the realizable gain of the terminals is based on locations within the beam. The signal power level allocated to each carrier is different from the power allocated to the other carriers.
