Abstract
The success of future satellite networks depends on the efficient use of scarce system resources, in particular on the available frequency spectrum. In this respect, the reuse of frequency bands in a multi-beam scenario has already created a breakthrough resulting in a significant increase of the system capacity. However, the related interference problems have to be solved by appropriate means to achieve the full potential of such a solution.
By several past and on-going ESA activities, advanced interference mitigation techniques have been investigated. Assuming ideal conditions, analytical and simulation results indicate that a substantial increase of the capacity might be obtained via full frequency reuse.
Aim of this project is now to evaluate these concepts in a more realistic and representative test environment, taking into account system and payload characteristics. To this end, a system demonstrator will be developed, which proves the feasibility and the benefits of different interference mitigation techniques.
