摘要

提出了大规模MIMO系统空时编码结合特征波束成形（STBC-BF）方案中的天线选择技术。发射符号空时分组编码后经天线阵列加权，形成特征波束，利用天线选择技术对发射天线和接收天线进行选择，接收端采用传统译码方法进行译码。该方案既可以获得空间分集增益和阵列增益，又能减少射频链路的数目，从而降低计算复杂度。仿真结果表明了该方案的有效性。

Abstract

An antenna selection scheme of space-time block coding combined with eight-beamforming (STBC-BF) in massive MIMO system was proposed.Transmit symbols were coded by space-time block coder

then the coded symbols were weighted by antenna array form eight-beam.The antenna selection technology was used to select the transmitting antenna and the receiving antenna

traditional decoding method was performed at the receiver.The proposed scheme can not only obtain the space diversity gain and array gain

but also can reduce the computational complexity by reducing the number of the RF links.Simulation results confirm the validity of the proposed scheme.
