|Abstract:||A method is implemented to compensate for signal correlation in transmitting antenna arrays of multiple-input multiple-output (MIMO) wireless communication systems. Based on the knowledge of the transmitting channel covariance matrix, a de-correlation transform is designed to remove spatial correlation and antenna mutual coupling in the transmitting antennas. Simulation results show that if there is no correlation in the receiving antennas, this method can be used to realise capacities equivalent to those under the independent and identically distributed (i.i.d.) channel conditions. Results reveal that when there is correlation in the receiving antennas, compensation is more effective when the numbers of elements in the transmitting and receiving arrays are large. For transmitting and receiving arrays with a fixed number of elements, compensation is more effective when the antenna separation is small. © 2010 The Institution of Engineering and Technology.|
