In this paper, we consider some open-loop and closed-loop transmit antenna array (TAA) systems under a spatially correlated fading channel environment. It has been shown that the proposed open-loop TAA system can achieve more than 3 dB signal-to-noise ratio (SNR) performance improvement at a bit error rate (BER) of 10−1 ~ 10−2 with a TAA of 9 antenna elements. This performance has been obtained by utilizing statistical properties of spatially correlated channels (or long-term spatial channel properties). We also propose some approaches for closed-loop TAA systems with feedback of partial channel information. Generally, the performance of the closed-loop TAA system exceeds that of the open-loop TAA system. The closed-loop TAA system can exploit the trade-off between the performance and the amount of feedback.
