Abstract

This study introduces an event camera-based optical camera communication system utilising pulse-shaped waveform modulation leveraging the camera's high temporal resolution and sensitivity. The proposed scheme demonstrates reliable performance under controlled indoor conditions with a fixed transmitter–receiver distance, achieving bit error rate values below 3.13 $\times$ 10 $^{- 3}$ at data rates of 100 bit/s with mid-range receiver bias sensitivity and mid-high transmitter illumination. Although the experiments tested only four symbols, the flexible design supports higher-order modulation, which has the potential for increased data rates and more efficient bandwidth utilisation.

基于事件相机的OCC系统中脉冲波形调制的评估

本研究介绍了一种基于事件相机的光学相机通信系统，该系统采用脉冲波形调制，充分利用了相机的高时间分辨率和灵敏度。所提出的方案在室内受控条件下，以固定的发射器-接收器距离展示了可靠的性能，在数据速率为 100 比特/秒、接收器偏置灵敏度为中档、发射器照度为中高的情况下，误码率值低于 3.13 × $\times$ 10 - 3 $^{-3}$。虽然实验只测试了四个符号，但灵活的设计支持更高阶的调制，从而有可能提高数据传输速率和带宽利用效率。
