A closed-form capacity bound for jointly correlated MIMO channel

Abstract

In this paper, a capacity bound for jointly correlated MIMO channel is investigated assuming full knowledge of the channel state information (CSI) at the receiver and statistical CSI at the transmitter. An eigenmode transmission strategy using statistical transmitter CSI is presented, and a closed-form capacity bound for eigenmode-based systems is derived. A relationship between the capacity upper bound and the permanent of the channel coupling matrix in eigenmode is established. Simulation results confirm the tightness of the obtained capacity bound.
