the performance of the multi-beam satellite systems with a new bandwidth sharing algorithm

An efficient resource allocation is important to guarantee the best performance with a fair distribution of multibeam satellite capacity to provide satellite multimedia and broadcasting services. in this way, available bandwidth and capacity problems in new satellite system likes multiinputmultioutput (mimo), exploring new techniques for enhancing spectral efficiency in satellite communication has become an important research challenge. in this aspect, multibeam or frequency reuse can be considered as a promising solution to solve spectrum scarcity problem. in this paper, a new bandwidth sharing algorithm for satellite systems under multibeam technique is proposed. furthermore, by using the above framework, capacity of multibeam satellite system based the number of antenna was simulated and compared them to obtain a solution for designing the next generation satellite systems. therefore, by using the multibeam and multi antennas satellite parameters considered in the first step, the bit error rate was achieved by 4qam and 4psk modulations based on the number of antennas.
