| Abstract(in English) | This study considers visible light communication between a digital signage and an image sensor. We have focused on the demodulation part of the communication system, which modulates data signals without interfering with the visual information displayed on the digital signage, and have studied a method to demodulate the transmitted data signals from the received image of the image sensor using machine learning with data sets that simulate noise, blur, and misalignment that may occur in the received images. In this paper, we propose to train the demodulation method on datasets with additional signal cells that cause inter-symbol interference on the simulated received images to acquire robustness against inter-symbol interference from surrounding cells of the signal cells to be demodulated. We also evaluate the obtained robustness of the machine learning model against inter-symbol interference. |
