In this paper, we analyze the performance of visible light communication system using rolling shutter CMOS sensor. For analysis, the effect of ISI (Inter-symbol Interference) on visible communication has been formulated. We validate our analysis through computer simulations.

Unlike conventional visible light communications (VLC) adopting photo detectors (PD), optical camera communications (OCC) employs cameras in detecting the transmitted data. Especially, the data rate of OCC can be enhanced by using the principle of rolling-shutter, which is the operating scheme of a CMOS image sensor. In this study, we consider a novel OCC system for high-speed real time video processing to transmit high speed data from LED and to acquire image utilizing rolling-shutter effect of CMOS image sensor. Also, we demonstrate the improved performance of proposed system using a test-bed.
