N2 - We analyze the performance of closed-loop transmit diversity systems in the presence of feedback delay and channel estimation error in Rayleigh time-selective flat fading. We formulate both the feedback delay and the channel estimation error as a function of Doppler spread, and derive the average bit error probability under such imperfect channel information. It is shown that the channel estimation error is more sensitive to system performance than feedback delay in slow fading environments.
