Combination of Spatial Multiplexing and Non-orthogonal Multiple Access NOMA

Large number of publications are devoted to non- orthogonal multiple access technology which is one of the main candidates for inclusion in the new international standards of wireless communication systems. The introduction of new multiple access technology brings with large number of unsolved problems in the field of signal processing. One of this is combining new multiple access technology with already well- established technologies, such as multiple antenna MIMO systems. The main goal of this work is to show possible combinations of MIMO and NOMA technologies. The results of computer simulations provide us to evaluate gain from the joint use of these both technologies.
