Optimization of number of base station antennas in downlink massive MIMO and analysis of imperfect channel state information by perfection factor

In the present days, there is a rapid growth of data rates in wireless communication but suffers from channel state errors due to imperfections in channel state information (CSI) which leads to a decrease in energy and spectral efficiency. In this paper, the perfection factor has been proposed to op...
