“…Massive MIMO is a Multi-user MIMO (Mu-MIMO) with a large number of Base Station (BS) antennas and users and it has less number of transmitter terminals than the BS antennas [11]. This system uses antenna arrays with a very large number of antennas elements that makes use of service antennas over active terminal and Time Division Duplex (TDD) operation on a large scale [12], [23]. This technology is an upgrade of the current MIMO (Mu-MIMO) and extract all the benefits of it but on a large scale.…”

“…Massive MIMO is the next Generation network that is expected to be lunch across the globe by the year 2020 [15]. The concept of Mu-MIMO System was proposed in 1991 by Richard Roy and Bjorn Ottersten [23]. Massive MIMO system components will have different ways of accessing higher frequency ranges and the motive of massive antenna setups are going to be direct-to device communication and ultra-dense deployments [24].…”

The term Massive MIMO means, Massive multiple input multiple output also known as (large-scale antenna system, very large MIMO). Massive Multiple-Input-MultipleOutput (MIMO) is the major key technique for the future Fifth Generation (5G) of mobile wireless communication network due to its characteristics, elements and advantages. Massive MIMO will be comprised of five major elements; antennas, electronic components, network architectures, protocols and signal processing. We realize that precoding technique is a processing technique that utilizes Channel State Information Technique (CSIT) by operating on the signals before transmitting them. This technique varies base on the type of CSIT and performance criterion. Precoding technique is the last digital processing block at the transmitting side. In this paper, linear and non-linear Precoding technique was reviewed and we proposed two techniques under each that is Minimum Mean Square Error (MMSE), Block Diagonalization (BD), Tomlinson-Harashima (TH) and Dirty paper coding (DPC). Four Precoding techniques: MMSE, BD, DPC and TH were used in the studies to power consumption, energy efficiency and area throughput for single-cell and multi-cell scenarios. In comparing the proposed techniques, in terms of energy efficiency and area throughput, reuse factor (Reuse 4) performs better than other techniques when there is an imperfect CSI is used.
