Massive MIMO Systems In Wireless Communication

In this paper we have presented an overview of Massive MIMO systems in wireless communication which are the breakthrough in wireless communication technology nowadays. MIMO systems are used to improve the noise and interference performances of a channel. In the paper, MIMO systems are used to expand channel capacity and BER are also highlighted. The discussion then proceeds further towards the limitations and advancements in this technology. In modern scenario massive MIMO includes merger of OFDM with MIMO. By the use of MIMO-OFDM, very high data rates are achieved.
