An efficient resource allocation is important to guarantee the best performance with a fair distribution of multi-beam satellite capacity to provide satellite multimedia and broadcasting services. In this way, available bandwidth and capacity problems in new satellite system likes Multi-Input-Multi-Output (MIMO), exploring new techniques for enhancing spectral efficiency in satellite communication has become an important research challenge. In this aspect, multi-beam 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 multi-beam technique is proposed. Furthermore, by using the above framework, capacity of multi-beam 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 multi-beam and multi antennas satellite parameters considered in the first step, the bit error rate was achieved by 4-QAM and 4-PSK modulations based on the number of antennas.
