In this paper, we investigate the impact of imperfect channel state information at the transmitter (CSIT) on the fundamental tradeoff of diversity and multiplexing in multi-input multi-output (MIMO) fading channels. We show that through power adaptation, a higher diversity gain as well as a more efficient diversity-multiplexing tradeoff can be achieved than the reported results in literature. Our analysis reveals that imperfect CSIT significantly improves the achievable diversity gain while enjoying the full spatial multiplexing gain.
