In the fifth generation (5G), the traditional restrictions that limit the capacity of wireless communication must be
overcome. Non-orthogonal multiple access (NOMA) is a promising solution capable of overcoming these constraints to meet
the requirements of 5G. The multiple-input multiple-output (MIMO) scheme that employs beamforming precoding technology
can achieves NOMA. In this letter, we proposed non-unity beamforming precoding based on maximum signal to leakage ratio
(SLR) algorithm as NOMA for multi-user MIMO (MU-MIMO) system. Then, we will compare between the proposed scheme
and the classical SLR-based on beamforming precoding algorithm. This paper evaluates the symbol-detection performance for
proposed and classical MU-MIMO beamforming over a Rayleigh fading channel and Rician fading channel. Simulation results
show that the proposed scheme has better performance than the classical scheme. And the Rician fading channel has
performance improvement until with low Rician factor value, compared to a Rayleigh channel.
