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。
This paper mainly studies several channel fading problems in wireless image transmission using UAVs and proposes a new encoding method that uses space-time coding to resist channel fading and improve channel capacity. Experiments show that it can significantly improve the utilization rate of frequency and effectively solve the quality problem of wireless image transmission in the experiment of wide area space.
