基于可见光通信的多语种同步语音解说系统

摘要

This paper proposes a multi-language real-time synchronous voice explaining scheme based on visible light communication(VLC).A multi-language real-time synchronous voice interpretation system is developed to realize multi-language simultaneous interpretation and real-time voice broadcastingas well as other functions,the system involves such technologies like highly efficient optical modulation and demodulation,channel time division multiplexing and ping-pong storage.Then the paper analyzes the bit error rate at different communication distance,communication rate and comparator threshold voltage,with a further analysis of the parameters on the impact of communication performance.%提出一种基于可见光通信(VLC)的多语种实时同步语音解说方案.搭建了基于可见光通信的多语种实时同步语音解说系统,采用高效光调制解调、信道时分复用和乒乓存储等技术,实现了多语种同步解说和实时语音广播功能.设计实验测试了在不同距离、不同通信速率和不同比较器阈值电压下误码率的值,进一步了分析各参数对通信性能的影响.
