  Multiple input multiple output (MIMO) system transmission is a popular
diversity technique to improve the reliability of a communication system where
transmitter, communication channel and receiver are the important elements.
Data transmission reliability can be ensured when the bit error rate is very
low. Normally, multiple antenna elements are used at both the transmitting and
receiving section in MIMO Systems. MIMO system utilizes antenna diversity or
spatial diversity coding system in wireless channels because wireless channels
severely suffer from multipath fading in which the transmitted signal is
reflected along various multiple paths before reaching to the destination or
receiving section.Parallel transmission of MIMO system has also been
implemented where both the real part and imaginary part of the original,
detected and the corresponding received data sequence has been described
graphically. The MIMO channel average capacity is achieved more than 80% for
dissimilar levels of impairments in transceiver when the value of kappa (Level
of impairments in transmitter hardware) reduces from 0.02 to 0.005. The
finite-SNR multiplexing gain (Proportion of MIMO system capacity to SISO system
capacity) has been observed for deterministic and uncorrelated Rayleigh fading
channels correspondingly. The core difference is in the high SNR level. It may
occur for two reasons: (a) there is a quicker convergence to the limits under
transceiver impairments (b) deterministic channels that are built on digital
architectural plans or topographical maps of the propagation environment
acquire an asymptotic gain superior than multiplexing gain when the number of
transmitting antenna is greater than the number of receiving antenna.
