초록

본 논문은 VLC (Visible Light Communication)의 새로운 응용 분야인 IoT 도어락 시스템을 위한 신호검출 방법을 제안한다. 보안성에 대한 이슈로 새로운 기술에 대한 수요가 있는 도어락 시스템에 VLC를 적용하기 위해서 극복해야 되는 사용자 인식을 위한 신호 검출 기법에 대해 설명한다. 이 시스템은 기존 인프라를 사용하여 가시광으로 통신을 수행하기 때문에 보안 및 높은 신호 검출 특성을 가진 것을 보인다. FFT를 사용한 신호 검출을 위하여 파일럿 신호를 기반으로 인증 채널에 접근한 사용자의 신호를 검출하고 이에 따른 채널 모델에서 오경보 확률과 검출 확률의 성능을 보인다.

This paper proposes a signal detection method for IoT door lock system which is a new application field of VLC (Visible Light Communication). This paper describes the signal detection technique for user recognition that needs to be overcome in order to apply VLC to door lock system which has a demand for new technology due to security issue. This system has security and high signal detection characteristics because it uses existing infrastructure to communicate with visible light. In order to detect the signal using FFT, the signal of the user who accesses the authentication channel based on the pilot signal is detected, and the performance of the false alarm probability and detection probability is shown in the channel model.
