An Implementation of Binary Frequency Shift On-Off Keying Modulation for Optical Camera Communication

Abstract

Optical camera communication (OCC) technique has been considered as an extension of visible light communication (VLC) with the advances on the development and commercialization of camera. It will be a promising technique for wireless communication which has been promoted as a candidate for the standardization issues by IEEE 802.15.7rl. OCC is the convenient way of transmitting data between light sources (LEDs, digital signage or other light emitting devices) and image sensor (camera, webcam) that are included in most of smart devices. In this paper, we introduce an OCC system from architecture to modulation scheme and application in indoor environment. Then, we propose a binary frequency shift on-off keying (BFSOOK) uses a pair of distinct OOK frequencies to transmit logic ones and zeros respectively for rolling shutter image sensors camera using light-emitting diode (LED) as the transmitter and camera of the smartphone device as the receiver. Within the scope of this technique, the new standard of Camera API with more advantages is used to resolve some issues related to OCC system.
