摘要

提出了一种基于OFDM的空时turbo编码(STTuC)增强数据传输技术。当系统流和奇偶校验流之间的衰落信道相关性较高时，STTuC在OFDM上的性能急剧下降。人工延迟加空时turbo编码(ADA-STTuC)在衰落信道相关性高的情况下降低了系统和宇称之间的衰落信道相关性，从而提高了性能。仿真结果表明，即使在完全相关衰落信道中，双发射天线和单接收天线的性能也有所提高。

Artificial delay added space time turbo coding on OFDM in correlated fading channel

This paper proposes an enhanced data transmission technique for space time turbo coding (STTuC) on OFDM. The performance of STTuC on OFDM degrades drastically when fading channel correlation between systematic stream and parity stream is high. Artificial delay added space time turbo coding (ADA-STTuC) lower the fading channel correlation between systematic and parity in high fading channel correlation case, which leads to performance improvement. Simulation results with two transmit antennas and one receiving antenna shows the performance improvement even in perfectly correlated fading channel.
