Abstract
A method of optimizing a link budget analysis (LBA) for a link comprising performing a first LBA based on a target modulation and coding pair (MODCOD) based on one or more link parameters, the MODCOD having a predetermined symbol energy to noise density ratio (Es/No), calculating a ratio of allocated bandwidth to a power equivalent bandwidth (PEB) for the link and converting the ratio to Decibels, determining whether additional energy is present by summing the Es/No for the link at the target MODCOD and the calculated ratio of allocated bandwidth to PEB, accessing a look up table to determine an optimal MODCOD for the link wherein if the sum is a positive value, selecting a MODCOD having a higher Es/No and if the sum is a negative value, selecting a MODCOD having a lower Es/No and altering one or more transmission or receiving parameters to apply the selected optimal MODCOD.
