چکیده :
Power efficiency and ability to high-speed modulation enables LEDs to transmit data in optical wireless communications. Optical camera communication (OCC) is a special type of VLC in which imaging sensor is using as a receiver instead of photodetector. Some challenges of such systems are the low data transmission rate and the light flickering. Recently under-sampled modulations are developed. In this paper to overcome flickering issue, we used one of under-sampled modulation named UPSOOK which enable us to modulate data with a frequency many times higher than the frame rate. Due to the presence of color filters in these sensors, the data transmission rate in OCC systems can be increased by using RGB LED and WDM. On the other hand, using windowing method to find optimum region for data detection, bit error rate (BER) decreased.
