Optimal Dynamic Capacity Allocation for High Throughput Satellite Communications Systems

In this letter, a simple engineering scheme for achieving optimal dynamic capacity allocation in geostationary and medium Earth orbit multi-beam high throughput satellite systems is presented. Exploiting smart gateway diversity setup and considering users' requested and gateways' offered capacities, we propose a theoretically optimal, based on Monge arrays, capacity allocation scheme for minimization of both system's capacity losses and rate matching performance metrics. This scheme has low complexity considering the appropriate sorting of system's offered and requested capacities. Finally, simulation results also confirm its optimality by presenting its identical performance with the much more complicated and time consuming exhaustive mechanism.
