摘要
针对无线语音通信系统中存在保密性低和抗干扰能力弱的缺点,设计了一套基于LED的可见光语音通信系统。介绍了白光LED语音传输系统的原理,设计了可见光通信系统的发射端和接收端电路,并通过实验验证了系统的性能。
Focuses on the disadvantage of low security and weak ability to against interference in wirelessvoice communication systems, this paper proposes a LED visible light voice communication system. Itintroduces the principle of white LED voice transmission systems, designs the circuit of the transmitting andreceiving end of visible light system, and validates the performence of system by doing experiment.
