This work evaluates interference mitigation mechanisms to enable the operation of self-organizing hybrid terrestrial-satellite networks with aggressive frequency reuse between terrestrial and also satellite links. The objective is to take advantage of the improved capacity and resilience to congestion of such networks while assuring and efficient use of the spectrum. In particular, single- and multi-user...
Whenever multibeam satellite systems target very aggressive frequency reuse in their coverage area, inter-beam interference becomes the major obstacle for increasing the overall system throughput. As a matter of fact, users located at the beam edges suffer from very large interference for even a moderately aggressive planning of reuse-2. Although solutions for inter-beam interference management have...
This paper presents a dynamic backhaul network in order to face some of the main 5G challenges such as 100% coverage, improved capacity or reduction in energy consumption. The proposed solution, elaborated within the SANSA H2020 project, is based on the seamless integration of the satellite component in a terrestrial network capable of reconfiguring its topology according to the traffic demands. The...
This paper deals with the problem of multibeam satellite pre-coding design under spectrum sharing constraints. These regulation restrictions allow the coexistence with other wireless services such as terrestrial mm-wave wireless local loop systems. This work focuses on the case where the satellite operator can use a certain frequency band whenever the signal power strength is limited over the coverage...
