For high speed wireless communication, data are transmitted with high spectral efficiency, high data rate and reliability. But due to Rayleigh fading, the channels suffer from lot of attenuation resulting in the reduction of Energy Efficiency (EE) and Spectral Efficiency (SE). The proposed system consists of MIMO using Closed Form Approximation (CFA) method. Multiple Input Multiple Output (MIMO) systems are form of spatial diversity in which the authors use multiple antennas at transmitter as well as receiver. In multipath channel, deploying multiple antenna techniques at both transmitter and receiver achieves high data rate without increasing the total transmission power or bandwidth.
