Rapid industrial sector growth looks forward to the upcoming communication technology of the fifth generation (5 G). The technology of Massive Multiple Input and Multiple Output (MIMO) has attained importance in the field of studies, This is one of the inevitable major components of the 5 G wireless tool. Due to the prospective benefit and its ability to send /receive information from various antennas at the same moment, the MIMO scheme is gradually being implemented in the field of communication.In 5G wireless communication systems, antenna arrays consisting of various elements became part of the normal setup.And such wireless communication systems are referred to as the MIMO scheme.By exploring redundancy across various transmissions and receiving channels, these array antennas can assist enhance the SNR. They also enable the spatial data in the scheme to be reused to enhance coverage. Multiple antennas, together with moment and frequency, use the spatial dimension without influencing system bandwidth demands.While the communication in general focuses on transmission multiplicity instead of traditional receiving multiplicity.Using the flat fading Rayleigh cha nnel, which can be applied when various transmitter antennas are used, the notion of orthogonal spacetime block coding is demonstrated. Here it is presumed that channel between various pairs of transmitter receiver antenna undergoes independent fading.5G can simultaneously serve multiple customers with high gain by providing different degrees of freedom (DOF). Increasing the system's Spectrum Efficiency (SE), Chanel Capacity (CC), Reliability, and SignaltoNoise Ratio (SNR).
