Realization of Spectral Efficiency with Multiple Input Multiple Output Systems for 5G and Beyond Technologies

Today, wireless communication systems have made great progress both in terms of efficiency and cost. Multiple Input Multiple Output (MIMO) system is an advanced system for 5th generation and beyond technologies. MIMO, 2X2, 3X3, 4X4 and so on. which can be achieved by communicating with very high data at the same time as thousands of different antennas. An increase of up to 10 times spectrum efficiency can be observed with MIMO, which is used to improve the efficiency, capacity and coverage of the wireless system. In this study, various evaluations were carried out by giving information about simulation activities obtained in the literature about bit rate / s / Hz / cell of spectral efficiency with Multiple Input Multiple Output systems in 5th generation and beyond technologies.
