Massive MIMO (also known as "Large-Scale Antenna Systems", "Very Large MIMO","Hyper MIMO", "Full-Dimension MIMO" and "ARGOS") enables a significant reduction of latency on the air interface with the use of a large excess of service-antennas over active terminals and time division duplex operation. We consider the downlink of a time-division duplexing (TDD) multicell multiuser MIMO system where the base stations (BSs) are equipped with a very large number of antennas. Assuming channel estimation through uplink pilots, arbitrary antenna correlation and user distributions, 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). The approximations are tight in the large system limit with an infinitely large number of antennas and user terminals (UTs), but match our simulations for realistic system dimensions. We further show that a simple EBF precoding scheme can achieve the same performance as RZF with one order of magnitude fewer antennas in both uncorrelated and correlated fading channels. Our simulation results show that our proposal is a better precoding scheme than the conventional scheme. Also, we have used two channel environment channels for further analysis of our algorithm given as Long Term Evolution Advanced (LTE-A) and another one is Millimeter wave Mobile Broadband (MMB) channel.
