Adaptive Transmit Diversity with Quadrant Phase Constraining Feedback

Abstract

An adaptive transmit diversity scheme with quadrant phase constraining feedback is proposed in this paper. with simple linear operations at both transmitter and receiver, the proposed algorithm can achieve better system performances with only 2M−2 bits of feedback information for systems with M transmit antennas. Theoretical performance bounds of the proposed transmit diversity scheme are derived. Simulation examples and theoretical analyses show that the proposed transmit diversity scheme outperforms not only the conventional open-loop transmit diversity techniques, but also some closed-loop transmit diversity techniques with more information transmitted in the feedback channel.
