Abstract

Massive (MIMO) multiple input multiple output is a concept of using hundreds of antennas at the same base station (BS) to communicate with tens of users simultaneously in the same time-frequency resource. Because of using large numbers of antennas at the BS, different (UE) user equipment become orthogonal to each other. Therefore, the data rate will be increased and low complexity signal processing mechanism could be applied. In this paper the effect of number of antennas on Massive MIMO system performance was investigated. The system has been evaluated for three different number of BS antennas (60, 90 and 120) with 30 users and a range of BS (30 to 120) with 13 users, and assumed that there is no line of sight, and then a Rayleigh fading channel has been used.
