Claim:
1. A system for assigning downlink frequency channels in a multi-beam satellite communications system, the system comprising: a frequency channel eligibility processor configured to identify a number of eligible downlink frequency channels for each of a plurality of modulation and coding groups; a resource estimation processor configured to estimate downlink resource unit demand for the each of the plurality of modulation and coding groups by identifying a cumulative guaranteed downlink rate for the each of the plurality of modulation and coding groups and a measured downlink traffic rate in excess of the cumulative guaranteed downlink rate for the each of the plurality of modulation and coding groups for a past defined time period; and a frequency channel assignment processor, in communication with the frequency channel eligibility processor and the resource estimation processor, and configured to select the each of the plurality of modulation and coding groups for frequency channel assignment in an order corresponding to at least one of the number of eligible downlink frequency channels or the estimated downlink resource unit demand for the each of the plurality of modulation and coding groups, wherein the frequency channel assignment processor is further configured to: assign first frequency channel time slots to the each of the plurality of modulation and coding groups to fulfill the cumulative guaranteed downlink rate for the each of the plurality of modulation and coding groups; and assign second frequency channel time slots, subsequent to the first frequency channel time slot assignment, to the each of the plurality of modulation and coding groups to fulfill the measured downlink traffic rate.
