Abstract

A spectrum-efficient block-ordered joint beamforming linear dispersion code(BO-JBLDC) is presented for MIMO(Multi-Input Multi-Output) wireless communication systems with correlated channels.The proped BO-JBI-DC method partitions the available transmit antennas into several blocks and applies linear dispersion code(LDC) on each block, which can decrease decoding complexity and increase code gain.Transmit and receive eigen-beamfomting was employed in the presence of deteriotative fading correlation.A novel post-ordered interference suppression and canceling decoder and its iterative scheme are presented to remove inter-substream interference and enhance the order of spatial diversity gain.The results show that BO-JBLDC can lower decodine comnlexitv and imrnuve spectral efficiency and reliability simificantly.
