Abstract


Massive MIMO is the most significant technology in 5G that improves spectral efficiency by employing massive number of antennas at the base station. This paper presents the variation of uplink achievable rates of massive MIMO systems in Rician fading channels using maximum ratio combining and zero forcing receivers for Perfect and Imperfect CSI. . The theoretical and approximated values of MRC and ZF receiver in Rician fading for Perfect and Imperfect CSI is formulated. With the results of simulations, it is shown that massive MIMO system can deliver high sum rate with the increase of antennas and also with the high Rician factor The impact of large-scale fading parameter in Rician fading using ZF receiver is analysed in this paper and compared with MRC receiver.
