Abstract

The performance of the MIMO eigenmode transmission system (EMTS) is very sensitive to the accuracy of channel state information and thus it is of practical importance to analyzing its performance when channel state information is corrupted under realistic system and propagation conditions. We lower bound the mutual information of MIMO EMTS with imperfect channel estimation and delayed quantized feedback in a spatially correlated continuous fading channel. Our results show that this lower bound is tight and can serve as a comprehensive guide to the actual performance of MIMO EMTS under practical operating conditions.
