ABSTRACT:
Systems and methods for improved use of idle power of each satellite repeater/transponder during low-traffic periods improve the overall link performance in multi-carrier, demand-assigned satellite communication systems through dynamic control and allocation of additional power to all signal carriers passing through each repeater when the total traffic load in the repeater is below a threshold. For satellite systems already in operation, the invention can be implemented and integrated into the existing feeder earth stations. For new systems, the invention can be implemented and integrated into the transmit section of individual satellite repeaters/transponders. The invention can be applied to new satellite systems to directly reduce the required satellite payload power for a given mission, thus substantially lowering the cost of the space segment. For existing systems, the benefits may be applied toward increasing the total number of carriers supported by the system, increasing the average quality and availability for the downlinks, increasing the system coverage and service area, or any combination thereof.
