초록

고속 광 센싱과 송신기로부터 넓은 범위의 가시광 수신에 적합한 가시광 통신 응용 서비스를 위해서 본 논문에서는 캐리어 변조 기반 가시광 통신 방식을 생각하고 32.768 kHz 저주파 캐리어와 4 MHz 고주파 캐리어 변조 기반 가시광 통신 회로를 각각 설계와 구현하여 설계된 회로의 신호 파형을 관측한다. 또한 구현된 캐리어 변조 기반 가시광 통신 프로토타입을 사용하여 여러 가지 성능 실험도 한다.

In this paper, the visible light communication (VLC) techniques based on the carrier modulation are considered in order to realize the VLC application service that has the functions of the high speed optical sensing and the wide range reception from VLC transmitter. The VLC hardware circuits based on the 32.768 kHz low frequency carrier and 4 MHz high frequency carrier are designed and implemented respectively, and the signal waveform generated from the implemented circuits are observed. In addition, various performance experiments are done with the prototypes.
