Method of optimizing resources by balancing power consumption and bandwidth consumption in a satellite or aircraft telecommunications system

摘要

The invention relates to a method of optimizing the resources used in a satellite or aircraft telecommunications system (onboard segment) by balancing the onboard power consumption and onboard bandwidth consumption. The method comprises at least the following steps: expressing the difference in consumption EdB between the consumption of onboard power and the consumption of onboard bandwidth as a function of the following terms: a quality indicator QaF' depending on the antenna system, onboard and on the ground and on conditions of propagation and interference of the medium: an informational term t dB depending on modem parameters; a term K' depending on onboard parameters such as the maximum incoming flux density and the bandwidth; a corrective term C dB characterizing the consumption of onboard power attributable to the upward noise which is amplified and transposed on board; and modifying at least one of the parameters QaF', K', t dB in order to tend toward the cancellation of the absolute value of the term EdB, i.e. to tend towards the designed value of zero for the difference EdB.
