| Abstract(in English) | Satellite/terrestrial integrated mobile communication system (STICS) is a system in which a user terminal directly connects both terrestrial and satellite base stations. STICS enables both an expansion of service areas and a robust communication service for large disasters. However, the cell radius of satellite system is large such as approximately 100 km, and thus, the capacity enhancement of the satellite subsystem for accommodating many users is needed. Therefore, in this paper, we propose an application of two methods, multiple-input multiple-output (MIMO) transmission using multi-satellites, and non-orthogonal multiple access (NOMA) for STICS, to realize the performance improvement in terms of system capacity and user fairness. Through numerical simulations, we show the system capacity and the user fairness are increased by the proposed scheme applying the two methods. |
