摘　　要：提出了大规模MIMO系统中的特征波束形成结合空时编码(space-time block coding combined with eigen-beamforming,STBC-BF)的发射方案。首先进行发射符号的空时编码,然后进行特征波束成形。接收端在两个正交的空间波束上进行空时译码,既可以获得空间分集增益,又可以获得阵列增益。理论分析和仿真结果都证明了该方案的有效性。A STBC-BF transmit scheme in massive MIMO system was proposed. Firstly, the signal was space-time block coded, then passed into the eigen-beamformers, respectively. At the receiver, the space-time decoding was performed on two orthogonal beams. The diversity gain and beamforming gain can be obtained simultaneously. Both theory analysis and simulation results confirm the validity of the proposed scheme.
