摘要
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。
This paper proposes a multi-language real-time synchronous voice explaining scheme based on vis- ible light communication（VLC）. A multi-language real-time synchronous voice interpretation system is devel- oped 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 differ- ent communication distance, communication rate and comparator threshold voltage, with a further analysis of the parameters on the impact of communication performance.
