摘　　要：以块空时分组编码的SC-FDMA虚拟MIMO系统为研究对象,理论推导给出块空时分组编码的SC-FDMA虚拟MIMO系统接收信号模型及虚拟MIMO接收机迭代均衡算法;仿真结果表明:迭代均衡接收机可显著提高块空时分组编码的SC-FDMA虚拟MIMO系统的链路可靠性。A virtual MIMO system based on single carrier frequency division multiple access （SC-FDMA） with blockspace-time block coding （B-STBC） is investigated. In this paper, the received signal model and a low complexity iterative equalization algorithm based on virtual MIMO system is proposed. Simulation results show that the proposed algorithm can obviously improve the transmission reliability.
