| Summary |
A visible light communication (VLC) system offers notable advantages, and leveraging image sensors as VLC receivers holds promise. The rolling shutter image sensor stands out as a popular candidate among these sensors. However, challenges arise from signal loss from inter-frame gaps or background scans. This paper addresses these issues by introducing a low-density parity check (LDPC) code and a corresponding code synchronization method suitable for LDPC decoding. Our approach employs a parallel transmitting sequence to achieve synchronization. Notably, the synchronization sequence is transmitted by modulating the luminance of the LED transmitter. Through experimentation, we validate the efficacy of our proposed method in mitigating signal loss. |
