Low Complexity Adaptive Design for Full-Diversity Full-Rate Space-Time Codes
2006
IEEE Transactions on Signal Processing
Full-diversity full-rate (FDFR) space-time codes for open-loop multiple antenna systems achieve both high data rate and good performance but come with very high decoding complexity. In this paper, we propose a low-complexity adaptive FDFR design for closed-loop multiple-input multiple-output systems. With only partial channel subspace knowledge at the transmitter, we adapt the open-loop FDFR code to the channel to maintain the special layer structure of the code at the receiver. That special
