There has been massive development in the quantity of wireless equipment’s in the last one decade requiring high device throughput and less energy consumption with the demand of increasing wireless equipment’s. Massive multi-input multi-output system cites to the approachfacilitatingtelecommunicationbase stations with a very huge quantity of antennas. These systems use several hundred antennas toserve large number of mobile users at the same time. LTE and Wi-Fi standards are embraced in massive MIMO. Massive MIMO has utility of increased capacity, improved throughput, energy&spectral efficiency making it suitable to be designed with less expensive and low power components. Massive MIMO employed in 5G applications uses awful number of antennas compared to current LTE systems.

Channel estimation, time-division duplexing, massive MIMO, pilot contamination.
