We analyze the impact of imperfect channel state information at the transmitter and receiver (CSITR) on the achievable diversity gain in multi-input multi-output (MIMO) fading channels with joint rate and power control. With rate control only, we consider the system with and without a minimum spatial multiplexing gain constraint, respectively. With joint rate and power control, we show that the achievable diversity gain can be improved significantly. The conducted analysis adopts the diversity-multiplexing tradeoff framework and uses the notions of diversity gain and multiplexing gain to study the impact of noisy CSITR in MIMO fading channels.
