Large-Scale Antenna Systems and Massive Machine Type Communications

International Journal of Wireless Information Networks, 2019
In this paper, we identify issues and possible solutions in the key area of large-scale antenna systems, also know as Massive Multiple Input Multiple Output (MIMO) systems. Additionally, we propose the use of Massive MIMO technology as a means to tackle the uplink mixed-service communication problem.
