%X In this paper, the impact of feedback delay on the performance of one closed multi-antennas system based transmit antenna selection is investigated. In such system, the receiver uses the maximum instantaneous SNR to select a target transmit antenna, then feedback the selected information to the receiver for transmit selection through the feedback link. The impact of feedback delay on the ergodic capacity, system outage probability and the bit error rate based on BPSK modulation are researched and the analytic results are presented. Simulations also demonstrate the effect of feedback delay on system performance.
