【摘要】 本文提出一种了利用HARQ的反馈信息进行天线选择发送分集的方案。该方案利用HARQ的ACK/NAK反馈信息作为天线切换的指令,从而能降低反馈负荷,同时系统只需要一套射频收发单元。理论分析及系统仿真表明,所提方案相比于单天线系统有显著的分集增益,其性能与传统的选择分集接近。更多还原

【Abstract】 In this paper,we propose a new transmit diversity scheme where we use the HARQ feedback message ACK/NAK as the antenna selection indicator.The proposed scheme can reduce the feedback load and requires only one RF transceiver.Both the analytical and simulation results indicate that the proposed scheme has significant diversity gain over the single antenna system and its performance is closed to the conventional selection combining diversity schemes.更多还原
