Popis:	In this paper, we investigate the performance of multi-beam high throughput satellite systems that employ the smart gateway diversity concept. The multi-beam satellite system is examined under the satellite system’s capacity losses, the impact of the channels’ atmospheric effects, the offered capacities of gateways and finally the requested capacities of users’ beams. To ameliorate the system’s performance, a novel flexible resource allocation algorithm is proposed which is based on the matching theory concept. Gateways and users’ beams are matched according to the aforementioned factors applying the deferred acceptance algorithm. Simulation results illustrate that the proposed matching scheme outperforms a less sophisticated fixed, i.e. without resource management, allocation scheme in terms of system’s capacity losses, rendering the former a very promising allocation mechanism for future satellite systems.
