Abstract
In this paper, we analyze the performance of closed-loop transmit
diversity systems in the presence of feedback delay and channel
estimation error in Rayleigh fading channels. 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.
