In this paper, we analyze the ergodic spectral efficiency upper bound of a large-scale MIMO and the key technologies, we derive approximations of achievable rates with linear precoding techniques, namely Zero Forcing (ZF), Matched Filtering (MF), Eigen-Beam Forming (EBF) and Regularized Zero-Forcing (RZF). We further show that a simple EBF precoding scheme can achieve the same performance as RZF with one order of magnitude fewer antennas. Our simulation results show that our proposal is a better precoding scheme than the conventional scheme. Also, we have used one channel environment channels given as Millimeter wave Mobile Broadband (MMB) channel.
