可见光通信技术是目前无线通信的研究热点，而调制驱动前端在可见光调制中起着十分重要的作用，它的主要有三极管、缓冲器方式，论文提出了用 NMOS 管驱动方式，并将照明用 LED 和传输信号用 LED 分开驱动的方式完成驱动前端设计，并制作出了可见光通信的发射系统。实验证明该方法在直射通信链路是可行的，且具有通信照明的双重功能。
可見光通信技術是目前無線通信的研究熱點，而調製驅動前耑在可見光調製中起著十分重要的作用，它的主要有三極管、緩遲器方式，論文提齣瞭用 NMOS 管驅動方式，併將照明用 LED 和傳輸信號用 LED 分開驅動的方式完成驅動前耑設計，併製作齣瞭可見光通信的髮射繫統。實驗證明該方法在直射通信鏈路是可行的，且具有通信照明的雙重功能。

Visible Light Communication（VCC）is a hot topic in the researh eara of indoor wireless communication,however the driving front end is playing a vevy important role for VLC modwlation,and there are the transis tovs and the buffer driving mode for the frontend,we proposed LED for communicution and LED lighting are separately driven using the freld offeat tran-sistors in this paper,and made out the wmissim part of VLC under this thenry.The experimeutal results shou that this method is feusible in the dired lommunicution links,and thesgstem has dual funetion of communication san lighting.
