  • Abstract
    In this paper, we consider transmit beamforming systems with finite rate feedback and feedback errors. We model the feedback channel as a uniform symmetric channel and analyze the effects of feedback errors on outage probability, bit error rate (BER), diversity gain, and array gain. Both analytical and simulation results show that feedback error with small probability will make the system behave badly at high signal-to-noise ratio (SNR).
