SYSTEM AND METHOD FOR SATELLITE LINK BUDGET ANALYSIS (LBA) OPTIMIZATION

摘要

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.

1. A method of optimizing a link budget analysis (LBA) for a communications link 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 a predetermined symbol energy to noise density ratio (Es/No); calculating, using the processor, a ratio of allocated bandwidth to a power equivalent bandwidth (PEB) for the communications link and converting the calculated ratio to Decibels; determining 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 using the processor; accessing a look up table (LUT) to determine an optimal MODCOD for the communications link wherein:
if the sum is a positive value, selecting a MODCOD having a higher Es/No; andif 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.
