摘要

本文提出了一种基于可见光通信(VLC)的模拟语音传输系统。在系统的发射端,通过电压-频率(V-F)转换电路,将模拟语音信号转换成频率信号,频率信号与信号的幅值成线性关系。在接收端,语音信号可以通过频率-电压(F-V)转换电路解调。最后对基于可见光通信的语音传输系统进行了测试,结果表明,输入输出波形一致,传输的语音可以无失真地接收到。试验结果表明,该设计是正确可行的。

A voice transmission system based on visible light communication
In this paper, we present an analog voice transmission system based on Visible Light Communication (VLC). At the transmitter of the system, by the Voltage-Frequency (V-F) conversion circuit, the analog voice signal is transformed into the frequency signal, which is linear with the amplitude of the signals. At the receiver, the voice signal can be demodulated by the Frequency-Voltage (F-V) conversion circuit. Finally the test of the voice transmission system based on visible light communication is carried out, which shows that the input and output waveforms are consistent, the transmitted voice can be received without distortion. The test result shows that the design is correct and feasible.
