A Novel Beam Selection Transmit Diversity Scheme for DS-CDMA System

摘要

In this paper, a novel beam selection transmit diversity (BSTD) scheme is proposed for the downlink trans- mission of frequency division duplex (FDD) based DS-CDMA system. As a combination of selection transmit diversity and steering vector based beamforming, the BSTD scheme provides diversity gain as well as reducing multiple access interference in downlink. Moreover, to have a better understanding, the perfor- mance of the BSTD is also compared with other schemes.
