摘　　要：红外光通信系统主要由红外发射端和红外接收端组成,以光为介质完成语音通信。系统中使用了MSP430F5529单片机作为工具对语音信号进行A/D,DSP,D/A,串口通信处理,在发射端应用了AM调制技术来降低误码率,提高通信的质量,进而使接收端得到的语音信号更加清晰。文章采用模块化思想制作硬件电路,同时将软件作为信号采集处理的工具,软硬结合共同完成光通信装置的理论分析和实物制作,传输的语音效果良好。Infrared optical communication system is mainly composed of infrared transmitting end and infrared receiving end, and completes voice communication with light as medium. The MSP430 F5529 single-chip microcomputer is to perform A/D, DSP, D/A and serial communication processing on the voice signal. AM modulation technology is applied at the transmitting end to reduce the bit error rate and improve the quality of communication, so that the receiving end can get the receiving end. The voice signal is clearer.In this paper, we use modular thinking to make hardware circuits and software as a signal acquisition and processing tool. The combination of software and hardware completes the theoretical analysis and physical production of the optical communication device, the transmitted speech effect is good.
