System and method for satellite link budget analysis (LBA) optimization

A system for optimizing a link budget analysis (LBA) for a communications link comprising:

• a transmitter configured to transmit a communications signal;
• a receiver configured to receive the communications signal and create a communications link between the transmitter and receiver, the receiver and transmitter located remotely from each other;
• and
• a processor configured to:
• perform 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 a predetermined symbol energy to noise density ratio (Es/No);
• calculate a ratio of allocated bandwidth to a power equivalent bandwidth (PEB) for the communications link and converting the calculated ratio to Decibels;
• determine whether additional energy is present in the communications link by summing the Es/No for the communications link at the target MODCOD and the calculated ratio of allocated bandwidth to PEB;
• access a look up table (LUT) to determine an optimal MODCOD for the communications link wherein:
• if the sum is a positive value, a MODCOD having a higher Es/No is selected;
• and
• if the sum is a negative value, a MODCOD having a lower Es/No is selected;
• and
• alter one or more transmission or receiving parameters to apply the selected optimal MODCOD;
• and
• perform a plurality of first LBAs based on a plurality of target MODCODs for a plurality of links sharing a common transmission or receiving hub;
• calculate a ratio of allocated bandwidth to a power equivalent bandwidth (PEB) a maximum allocated bandwidth from among the plurality of links and a maximum PEB from among the plurality of links and converting the calculated ratio to Decibels;
• and
• determine whether additional energy is present in the plurality of communications links by summing the Es/No for the most disadvantaged communications link at the target MODCOD and the calculated ratio of allocated bandwidth to PEB based on the maximum allocated bandwidth and PEB from among the plurality of links.
