    • 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.

    • A payload design for a multi-spot-beam satellite communication system includes a plurality of uplink spot beam receivers and downlink spot beam transmitters, and a broadcast transmitting subsystem capable of transmitting a broadcast beam to an entire system geographical service area. An input filter-switch-matrix (IFSM) controllably selects input IF signal bands for routing to an on-board digital signal processor-router (DSPR). The DSPR subsequently routes all received point-to-point and broadcast data packets to the appropriate downlink spot or broadcast transmitting subsystems for transmission thereof. The broadcast downlink allows broadcast transmissions to occur at the highest efficiency possible, while also allowing for flexible provision of surge capacity for point-to-point transmissions on previously exhausted spot beams by selective use of the broadcast beam for such point-to-point transmissions.

    • A satellite payload architecture for interactive data distribution and broadcasting services preferably for use in the emerging EHF (20-60 GHz) frequency bands. The system allows many individual service-program providers to transmit their service-program data to the satellite, on a bandwidth-on-demand and as-needed basis, directly from their premises through low-power, low-cost broadcast satellite terminals. The satellite payload utilizes high-gain spot beams for low-cost uplinking, digital regeneration and multiplexing of the individual received service-program data into MPEG transport streams, and broadcasting these in a DVB-compatible format via full-area broadcast beams to very small, low-cost end-user satellite terminals. All end-user satellite terminals are also equipped with transmit capability of a reverse-channel in support of interactivity-communications and network signaling/control functions. The proposed system will provide low-cost interactive data distribution and broadcasting services to thousands of small and large content-providers to reach their target customers.
