Adaptive resources allocation for flexible payload enabling VHTS systems: Methodology and architecture

摘要

Very High Throughput Satellites (VHTS) are optimized satellite systems that will meet the demands on increasing data traffic. VHTS outperforms the capacity of traditional systems that provide FSS and MSS (Fixed and Mobile Satellite Services, respectively) which use contoured regional footprints. VHTS aims at achieving 1 Terabit/s per satellite in the near future, and are based on multi-spot coverage with frequency and polarization reuse schemes using larger bandwidths in the feeder link in the frequency Q/V bands or by optic links. These systems provide higher satellite links capacity with a reduced cost per Gpbs-in-orbit. Since traffic demand is not always the same in the service area and it may change over time, new flexible payload concepts are required. In this sense, this contribution presents the study of a flexible payload concept, the methodology for the adaptive algorithm to be used during the on-line or off-line processes for optimal resources allocation and the architecture for adaptive resources allocation as well with a set of preliminary results.
