| 摘 要： | 针对多输入多输出正交频分复用(MIMO-OFDM)通信系统，提出了一种简单而有效的空频编码算法：时域循环延迟法，即利用OFDM时域帧信号的循环延迟实现空频编码．理论分析和计算机仿真结果表明：该空频编码算法不仅能获得完全分集增益(包括空间分集和信道多径分集)，而且还具有与发送天线数量无关、计算量小和实现容易等优点．

| Abstract: | This paper proposes a novel space-frequency coding scheme, called spac e-time cyclic-delay coding (STCDC), for multi-input multi-output orthogonal freq uency-division multiplexing (MIMO-OFDM) systems over frequency-selective fadi ng channels. Theoretical analysis and computer simulation results show that STCDC- O FDM can achieve the maximum diversity (both spatial and multipath diversities) a nd has the advantages of being independent from the number of transmit antennas and having a lower implementation complexity. |
