Broadband multibeam satellite radio communication system with improved reuse of frequencies on the forward channel, and associated method for reuse

摘要

A broadband multibeam satellite radio communication system is configured to cover a geographical service area that is broken down into a plurality of transmission spots that are each made up of a central internal area and a peripheral area. A first polarization state and a second polarization state are respectively allocated to the spots of a first grid G1 and the spots of the second grid G2. One and the same main band BP of frequencies is allocated wholly to each central internal area. The coverage of the quadruple points service area is a pavement of elemental useful surfaces or coverage meshes having the shape of a parallelogram.
