| Summary |
A rolling shutter based visible light communication (VLC) system is possible to achieve high data rate by utilizing characteristics of rolling shutter image sensors, but some signal loss occur. In this study, we propose a synchronization method to decode a loss correct code in a rolling shutter based VLC system. To synchronize the received signal with the transmitted signal, we employ a combination of pulse width modulation (PWM) and Barker codes. The PWM technique helps in aligning the timing of the received signal with the transmitted signal, while the Barker codes provide a correlation property that aids in identifying the synchronization points. The experimental results show that this synchronization method enables us to use loss correct codes. Additionally, the bit error rate depends on a parameter of image processing on received images and the way to set a posteriori probabilities in the decoding. |
