Abstract
This paper presents an efficient and practicable MIMO transceiver in which transmitter antenna selection is applied to minimum mean-squared-error V-BLAST (MMSE VBLAST) detector and GMD precoding through limited feedback channel. The method compensates the deficiency of the GMD algorithm under ill-conditioned channel and improves the BER performance further. For over 4 £ 5 antenna selection, the proposed antenna selection scheme can save more than 50% computational complexity compared with that of the exhausting method. Moreover, efficient precoder quantization and reconstruction are also analyzed and evaluated with satisfactory performance. From the simulation results, the proposed transceiver can achieve over 6 dB SNR improvement over the open-loop V-BLAST counterparts at BER=10¡2 under i.i.d. channel.
