Massive MIMO is used in a new generation wireless technology and a method to improve the spectral efficiency (SE) of communications systems. Nowadays, because of the users and applications that are always increasing day by day the improvement of wireless technology shall be in line according to demand. In this paper, pre-coding technique used to optimize spectral efficiency and the number of user as a function of the number of antenna with different interference conditions are investigated. From the simulations, SE per cell for pre-coding technique and corresponding number of scheduled users can be seen. As the number of antenna at base station (BS) increases, the SE will also increase. The number of scheduled users depends on the inter-cell interference condition strongly. © 2016 IEEE.
