| 摘 要： | 提出了一种基于OFDM达到最大可达分集增益的空频码设计方案。该编码利用正交频分复用把频率选择性衰落信道变换成平衰落信道的特性，同时引入了基于多天线的空间分集和基于时延扩展的频率分集，比空时编码具有更高的分集增益。

| Abstract: | A novel design of OFDM-based space-frequency codes is proposed such that the maximum achievable diversity gain is available. Because using OFDM, a frequency-selective fading channel can be transformed into multiple frequency-flat fading sub-channels, in the coding process, spatial diversity (due to multiple antennas) is integrated with frequency diversity (due to delay spread), therefore, the proposed code can provide higher diversity gain than space-time code alone. |
