Abstract

This paper investigates the sum-rate of the ongoing active research area of 5G Technology – Massive Multiple-Input Multiple-Output (MIMO) system receivers based on CSI. For the uplink, by assuming that the base station (BS) deploys zero-forcing (ZF) or maximum ratio combining (MRC) receivers, we present the achievable sum-rate for both receivers with imperfect and perfect channel state information (CSI). In case of Imperfect channel state information, to find the characteristics of channel, channel estimation is done by transmitting pilot symbols.  Moreover, on the power scaling law, theimpact of channel state information is also characterized and numerical analysis is obtained for combiner. The aim of this paper is to compare how receivers perform well in case of imperfect and perfect CSI and how increase in the number of antennas effects the power of the user.
