中文摘要：
针对多入多出（MIMO）相关信道，提出联合波束成型分组排序线性离散码（BO—JBLDC）及其解码方法．发送天线被分割成多个组，每组进行独立的线性离散码（LDC）编码来获得空分复用增益．采用发送和接收特征波束成型降低信道相关性的影响．提出新的后排序分组干扰抑制与抵消解码方法及其循环迭代机制，消除组间干扰，使得各组均获得满接收分集增益．结果显示BO—JBLDC能获得高频谱效率并适用于任意天线配置，尤其在大天线数、高速率情况下可以明显降低解码复杂度，提高编码增益。
英文摘要：
A spectrum-efficient block-ordered joint beamforming linear dispersion code （BO-JBLDC） is presented for MIMO（Muld-Input Muld-Output） wireless communicadon systems with correlated channels. The proposed BO-JBLDC method parddons 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-beamforming was employed in the presence of deteriorative fading correladon.A novel post-ordered interference suppression and canceling decoder and its itemdve scheme are presented to remove inter-substream interference and enhance the order of spatial diversity gain. The results show that BO-JBLDC can lower decoding complexity and improve spectral efficiency and reliability significantly.
