Multiple input multiple output (MIMO) system transmission is a populardiversity technique to improve the reliability of a communication system wheretransmitter, communication channel and receiver are the important elements.Data transmission reliability can be ensured when the bit error rate is verylow. Normally, multiple antenna elements are used at both the transmitting andreceiving section in MIMO Systems. MIMO system utilizes antenna diversity orspatial diversity coding system in wireless channels because wireless channelsseverely suffer from multipath fading in which the transmitted signal isreflected along various multiple paths before reaching to the destination orreceiving section.Parallel transmission of MIMO system has also beenimplemented where both the real part and imaginary part of the original,detected and the corresponding received data sequence has been describedgraphically. The MIMO channel average capacity is achieved more than 80% fordissimilar levels of impairments in transceiver when the value of kappa (Levelof impairments in transmitter hardware) reduces from 0.02 to 0.005. Thefinite-SNR multiplexing gain (Proportion of MIMO system capacity to SISO systemcapacity) has been observed for deterministic and uncorrelated Rayleigh fadingchannels correspondingly. The core difference is in the high SNR level. It mayoccur for two reasons: (a) there is a quicker convergence to the limits undertransceiver impairments (b) deterministic channels that are built on digitalarchitectural plans or topographical maps of the propagation environmentacquire an asymptotic gain superior than multiplexing gain when the number oftransmitting antenna is greater than the number of receiving antenna.
