For our simulations, we set up a massive MIMO base station with many antenna terminals (16 to 512). We assume that all the antenna terminals are communicating with 128 single active users simultaneously. We have considered various antenna configurations with different modulation techniques (QPSK, 16QAM, 16QAM) for conducting the simulations. The system¡¯s bandwidth is set to 20 MHz, whereas a carrier frequency of 2.5 GHz is used. A perfect channel state information (CSI) is assumed between the user and the base station, and the Rayleigh fading channel model is used for simulations. We have compared our proposed algorithm with traditional schedulers like Proportional Fair (PF) and Round Robin (RR) algorithms for analysis. In addition, we have used ZF and MMSE precoding to reduce the effect of multi-user interference and to simplify the processing required at the receiver.
