- Abstract
- Multibeam satellite networks can extend the service coverage as deploying its spot beam. It is important to allocate the appropriate resources to downlink multibeams to prevent the unnecessary waste of resources in the satellite system. This paper presents an optimum beam allocation scheme for multi-spot beam satellite system, as beam bandwidth to be allocated is controlled dynamically. We apply the Lagrange theory to obtain the optimization formula for bandwidth allocation of each spot beam in order to meet the total bandwidth constraint. Eventually we can find out the optimum beam profile respect to bandwidth. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2011.
