Satellite Communication: Key Enabling Technologies

35390

Satellites have proven to be indispensable for universal communication networking in support of a variety of personal, commercial,and security applications. In an attempt and effort to remain competitive with terrestrial systems, in the context of increasing requirement for the future communication systems. The rapid increase of capacity of terrestrial link in terms of generations (1G to 5G in 2020) can be analogous to satellite communications. The first generation (1G) having a capacity of 5-50 Gbps per satellite, 2010-2020; the second generation (2G) satellite 50-500 Gbps, and 2020-2030; as the needs increase, for instance, as far future needs of the communication for Mars human community, this can be considered as third generation (3G) satellite 0.5-5 Tbps. SatCom are trying to follow the progress in terrestrial in such as: Multicarrier waveforms use, Full Duplex,SDN, MmWave, MIMO technologyand profit from the significant research achievements in the area of multiple antenna techniques. This work presents an overview of technologies that revolution terrestrial communication systems and considered as key technologies for 5G with the possibility of its application in satellite communication.
