摘　　要：主要研究了利用无人机进行无线图像传输中的几种信道衰落问题,提出了运用空时编码技术抵抗信道衰落、提高信道容量的一种新编码方式。试验表明,它可以使频率的利用率显著提高,有效解决广域空间实验过程中无线图像传输的质量问题。The main research is carried out on the problems about the fading of several signal channels in the wireless image transmission by using UAV （unmanned aerial vehicle）, and a new coding method is proposed by using the space-time coding technology to resist the signal channels＇ fading and increase the channels＇ capacity. The test shows that it can significantly improve the utilization ratio of the frequency, and effectively solve the quality problem of the wireless image transmission in the process of the experiment for the wide area space.
