This paper elucidates the fundamentals of visible light communication systems that use the rolling shutter mechanism of CMOS sensors. All related information involving different subjects, such as photometry, camera operation, photography and image processing, are studied in tandem to explain the system. Then, the system performance is analyzed with respect to signal quality and data rate. To this end, a measure of signal quality, the signal to interference plus noise ratio (SINR), is formulated. Finally, a simulation is conducted to verify the analysis.
本文阐述了利用CMOS传感器滚动快门机制的可见光通信系统的基本原理。同时研究了所有涉及不同主题的相关信息,如光度学、相机操作、摄影和图像处理,以解释该系统。然后,针对信号质量和数据速率对系统性能进行了分析。为此,制定了一种信号质量度量标准,即信号干扰加噪声比(SINR)。最后,进行了仿真以验证分析结果。
