Abstract

Signaling for optimum mutual information with limited feedback of channel state information is studied for the case when multiple transmit and receive antenna arrays are used to form multiple input multiple output channels. A simple mean square error based approach for finding near optimum signaling is suggested and its performance studied. Prior to limiting, the channel estimates are assumed perfect and delay in obtaining these estimates is ignored to focus on the effects of limited feedback.
