Capacity enhancement on optical camera communication with clock divider-mounted multi-cameras

Abstract

This paper proposes a technique of sampling-rate retrieval using multi-cameras with a lower frame rate than the symbol rate on an optical camera communication (OCC) with a clock divider. This proposed technique applies the characteristics of the integral sampling method that occurs when an image sensor-based camera receives the optical signal. The technique realizes the demodulation of the optical signal having a larger bit rate than the frame rate of the camera. Employing the proposed technique can achieve the transmission capacity of the number of cameras times frame rate per camera.
