Comprehensive Review on Performance Analysis for Satellite Communication MIMO Over Terrestrial Communication MIMO

ABSTRACT This paper presents a thorough review on technical and physical comparison between the implementation of satellite MIMO (multiple‐input multiple‐output) and terrestrial MIMO. The technological improvements in satellite MIMO over terrestrial MIMO which are absent in related previous works are additional with this survey paper. Most of the applications for heterogeneous user cases are feasible due to diversity performances and shortening the digital divide with facility of higher data rate capacity to remotely located and underserved areas. Over and above that suitable antenna design, perspectives to achieve satisfactory performance metrics like number of ports, slot effects, isolation factor, metamaterial are considered, while multiple antenna elements are also carried out for executing MIMO performance over satellite. Adaptive beamforming and multiplexing are the potential characteristics of MIMO technology which makes the device more feasible for high potential applications of satellite communication (SatCom) in various applications that demand higher capacity and enhanced coverage for ultrareliable wireless communication system. Various constellation satellites such as LEO (low earth orbit), MEO (medium earth orbit), and GEO (geostationary earth orbit) are categorized according to their altitude, elevation angle, and their applications. Exploitation of diversity performance to accomplish the critical services along with global coverage is an excellent service provided by satellite MIMO communication system. Furthermore, challenges associated with installation of MIMO with SatCom are analyzed, and benefits along with difficulties are introduced.
