“…Theoretical analysis of the MIMO channel has shown that the best results are obtained when the number of receiving antennas at the base station

is greater or equal to the total number of multiplexed data streams of all users, which is usually equal to the total number of transmitting antennas of all users

[ 6 , 11 , 12 , 13 , 14 , 15 , 16 ]. This conclusion has been originally obtained for a single user system [ 8 ], where it is shown that when the condition

is met, the system bandwidth increases linearly from the number of transmitting antennas.…”

The article is devoted to multiple-input multiple-output antenna systems, also called MIMO systems, which are widely used in wireless communication systems. In this article we consider a case when the MIMO system works in overloaded mode. In this mode MIMO systems can be considered as a system with non-orthogonal multiple access NOMA. The main goal of this article is to analyze this interesting case using statistical computer simulation. Based on the analysis of the capacity of a discrete-continuous multiuser MIMO uplink channel, the possibility of such systems functioning in overload mode is proved.
