| 摘 要： | 自由空间紫外光通信技术基于紫外线日盲特性,相对无线通讯技术具有灵活、难以截获、抗干扰性强、并具备一定的非视距通讯能力等诸多特点,在军事通讯领域有着巨大的优越性.然而,紫外光通信的调制解调技术以及语音传输是整个系统的关键难点.通过对大气传输特性、光源发光特性的研究,研制出一套基于二进制移频键控(2FSK)方法的调制系统.可以对语音信号进行有效的调制.

| Abstract: | Compared with the conventional communication systems,the technology of ultraviolet communication based on sun-blind characteristic of ultraviolet ray has unique properties,such as includes facility,non-intercept,powerful interference immunity and non line-of-sight communications,which is adept at military application. However,the modulation-demodulation of ultraviolet and voice transmission are the key technologies.After researching on the atmospheric transmission characteristic and light source characteristic,a modulation system based on 2FSK has been developed.This system could modulate the voice signal effectively. |
