在多输入输出（Multiple-InputMultiple-Output，MIMO）系统中提出一种块分组编码与VBLAST的联合编码方案，该方案对最先检测的2层数据流采用块分组编码，其余层采用垂直分层空时码（Vertical Bell Layered Space-TimeCod，VBLAST）的编码方式，MIMO系统同时具有了空时分组码（SpaceTimeBlockCode，STBC）可以降低误码率的优点与VBLAST能够提高系统容量的优点。块分组编码将数据符号按层分块后交叉通过不同的天线对发射，数据流之间产生了一定交织效果，使编码获得了更好的分集增益，在接收端结合QR分解的最大似然解码算法进行解码。仿真结果表明该联合编码方案与传统的Alamouti编码和VBLAST的联合编码方案相比误码率性能有较大改善。“,”A block coding and VBLAST joint encoding scheme is proposed in multiple-input muRlple-output （MIMO） systems. In this scheme, the block coding is used for the first two layers detected and the VBLAST coding scheme is used for other layers. The system has the advantage of lower BER of STBC and higher capacity of VBLAST. The block coding symbols are transmitted decussately through different antenna groups after blocking by layers, then, there are some interleaving effects between the data flows so as to get better diversity gain. Decoding is done by the receiver with QR decomposition for maximum likelihood decoding algorithm. Simulation results show that the proposed joint encoding scheme improves the BER remarkably comparing with Alamouti coding and VBLAST hybrid coding scheme.
