Massive MIMO Systems for 5G Communications

Abstract Massive MIMO will improve the performance of future 5G systems in terms data rate and spectral efficiency, while accommodating a large number users. Furthermore, it allows for 3D beamforming order to provide more degrees freedom increase high-throughput is expected advantages compared other solutions energy efficiency. This be achieved by focusing radiation towards direction intended users, thus implementing simultaneous transmission many users keeping interference low. It can boost capacity conventional antenna solution, resulting efficiency up 50 times greater than that provided actual 4G technology. However, take full advantage this technology overcome challenges implementation real environment, complicated radio system required. The purpose work present evolution simple introductory way investigate potential enhancements.
