Power available for each downlink beam is typically set by an associated amplifier on the satellite, and total transmit power cannot be dynamically distributed across different spot beams. An embodiment of the present invention overcomes this distribution limitation by using multiple replicas of a single signal as input to a multi-port amplifier that allows transmit power to be dynamically distributed across the different spot beams. The replicas may be de-correlated through techniques such as selectively delaying some of the replicas. This power distribution effectively allows dynamic allocation of capacity between areas serviced by different beams. Offered load in different beams can be predicted and used to set the attenuation values appropriately and the attenuation values may also be controlled remotely."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Flexible coverage areas for forward link signals in a spot beam satellite communication system","description":"Conventional spot beam satellites transmit downlink beams that each correspond to a separate and unique uplink signal.
