A Novel Full-Diversity Full-Rate Transmit Beamforming Systems Combined with V-BLAST over Correlated Fading Channels

摘要

In this paper, we propose a novel transmit beamforming algorithm combined with vertical Bell laboratories layered space-time (V-BLAST) over correlated fading channels. Using the antenna groups at the transmitter, not only spatial multiplexing gain but also beamforming gain can be achieved. We encode the transmit signals in order to enhance the diversity gain compared with conventional V-BLAST system combined with beamforming without changing the number of antennas. Simulation result shows that our proposed algorithm provides a significant reduction in the BER compared with the conventional V-BLAST and transmit beamforming combined with V-BLAST without encoding transmit data.
