초록

무선 가시광 통신 기술은 실내 또는 수중에서 고속 통신 서비스가 가능하여 많은 주목을 받고 있다. 그러나 가시광에 대한 해수채널의 통신 성능은 현재의 가시광 파장영역 광원과 광 검출기 기술의 한계와 수중 통신채널의 변화로 인한 여러 가지 제약사항들 때문에 실용화를 위해서는 극복해야 할 문제점들이 존재한다. 본 논문에서는 직선상의 가시영역에 있는 해수 환경에서 신호 대 잡음비와 비트 오류율을 분석하였다. 데이터 속도, 통신거리, 감쇠계수등과 같은 파라미터들의 영향에 대하여 연구하였으며, OOK와 L-PPM 변조기법을 적용한 시스템의 모델링과 전산모의를 통하여 수중환경 통신에 대한 강점과 제한점등을 기술하였다.

The wireless visible light communication technology has received great attention for high-data rate services in the room and underwater. However, performance of a visible light seawater link is limited by multiple constraints from the current light source and detector technology, and underwater channel conditions. In this paper, performance of the line of sight underwater link was analyzed in terms of signal to noise ratio and bit error rate of the detector. Roles of different parameters such as data rate, transmission distance, and attenuation coefficient, are studied. Through the modeling and simulation of the OOK and L-PPM modulation technologies for undersea environment application, the advantages and limitations are described in detail.
