Claim Text:
1. A method of optimizing a link budget analysis (LBA) for a communications link within a communications system having a plurality of communications links comprising: performing, using a processor, a first LBA based on a target modulation and coding pair (MODCOD) that is selected based on one or more transmission or receiving link parameters, the MODCOD having at least one of a predetermined symbol energy to noise density ratio (Es/No), a target setting of a power amplifier, and a target antenna size; determining, by the processor, an excess margin from the first LBA and increasing or decreasing a maximum available MODCOD based on whether the excess margin has a positive or a negative value; performing, by the processor, a second LBA using the increased or decreased maximum MODCOD and iteratively repeating increasing or decreasing the maximum available MODCOD and performing a subsequent LBA using the increased or decreased maximum available MODCOD; calculating, by the processor a ratio of allocated bandwidth to a power equivalent bandwidth (PEB) and adjusting at least one of the MODCOD, amplifier power, and antenna size based on the calculated ratio; determining, by the processor, whether additional energy is present in the communications link by summing a contribution to a final ratio of allocated bandwidth to PEB of the communications system made by each of the plurality of communications links; accessing a look up table (LUT) to determine an optimal MODCOD for the communications link wherein at least one of the following actions is performed by the processor: altering one or more transmission or receiving parameters to apply the selected optimal MODCOD, amplifier size, or antenna size.
