Abstract

A method has been introduced to implement the optimum transmission strategy in MIMO systems. Based on the knowledge of the transmitting channel covariance matrix, a de-correlation transform has been 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 array, this method can be used to obtain the i.i.d. channel capacity of a MIMO system. Results also reveal that when there is correlation in the receiving array, compensation is more effective with larger transmitting and receiving arrays. For transmitting and receiving arrays with a fixed number of elements, compensation is more effective when antenna separation is small.
