Abstract:

The article analyzes two ways of managing information overloads: managing information flows and adapting parameters using an onboard active phased array by using on board m transmitters of different power, using on board the same power amplifiers.

The task of energy distribution of the repeater between transmitters was solved by statistical testing.

It is shown that, for example, with an acceptable level of relative information losses of 1%, the use of transmitters with different power and groups of identical amplifiers of different volume makes it possible, all other conditions being equal, to increase the network capacity in the considered example by 40% and 70%, respectively. The best results are obtained by using groups of identical power amplifiers. It is shown that the problem of dealing with information overloads in satellite communication systems is much more acute, and it is much more difficult to solve than in terrestrial networks.
