| 摘 要： | 多输入多输出（MIMO）技术是最近几年发展起来的无线通信技术。目前利用MIMO技术提高短波通信的传输速率和可靠性的研究已经开展。着重研究了MIMO OFDM（交频分复用）短波无线通信的同步技术，利用截断的Suehiro序列构成的训练符号完成了系统的同步捕获。仿真结果标明，与Mody算法相比，该方案在性能相近的情况下可提高系统的频谱效率。

| Abstract: | The multiple-input multi-output(MIMO) is a new technique in the wireless communication.Now the HF communication systems using MIMO technique to improve the data rate and reliability are under study.The synchronization of the MIMO OFDM HF wireless communication systems is investigated and a synchronization acquisition method using a training symbol consisted of the truncated Suehiro sequences is presented.The simulation result shows that the scheme has a higher spectral efficiency than that of the Mody with almost the same performance. |
