Abstract: Effect of impaired channel information on received SNR over Multiple Input Multiple Output (MIMO) channel was investigated. MIMO channel was converted into equivalent independent parallel channels through Singular Value Decomposition (SVD) of the channel matrix. Levels of degradations of MIMO channel efficiency due to impairments in the available channel information at the transmitter and the receiver has been shown through simulations. It has been observed in the simulation that maximum received SNR is obtained when transmitted signal distribution among transmit antennas and received signal combination is matched with channel gains of the equivalent parallel channels.
