MIMO system channel capacity with input transformation

Multi input multi output (MIMO) antennas system has been proved the best candidate for providing high data rate over broadband wireless channel. It requires the same amount of transmit power and bandwidth as single input single output (SISO) antenna system required. In general, input signal is considered to be uncorrelated when deriving the channel capacity of MIMO system. Correlation between input data reduces the channel capacity for MIMO system. In this paper, we proposed a transformation on input data which decorrelates them and enhance the channel capacity. Simulation results show that the transformation on input data increases the channel capacity as it decorrelates the input signal.
