摘　　要：利用频谱搬移原理,采用信号模拟调制与解调技术,设计了抗干扰的可见光通信演示仪.该演示仪由模拟信号调制发射电路和信号接收解调电路构成,可在正常的室内照明环境中与外界强光干扰下正常工作.By using the principle of spectrum shifting and adopting the technology of analog modulation and demodulation,an anti-interference visible light communication demonstrator was designed.The demonstrator was composed of an analog signal modulation transmitting circuit,a signal receiving demodulation circuit,etc.,which could work in the normal indoor lighting environment with external light interference.

关 键 词：幅度调制 频谱搬移 可见光通信 光电转换
