Satellite interference evaluation: joint effect of modeling earth station locations and earth station antenna sidelobe gains as random variables

By September 3, 2014 Industry News No Comments

SUMMARY

When several satellite communication systems share the same frequency band, each system operates under the aggregate interference generated by the others. In this interfering environment, interference calculation procedures in which worst-case situations and simplifying assumptions are considered are commonly used. Given that the geostationary satellite orbit and the frequency spectrum are limited resources, it is important to consider alternatives that lead to a more precise interference evaluation. One of these alternatives is the use of a probabilistic methodology, in which some of the parameters involved are modeled as random variables. This work considers the specific case in which the earth station geographic locations and the sidelobe gains of their antennas are modeled as random.
