Abstract

This paper is a study result on long distance transmission of underwater acoustic sensor data over cable. The data transceiver is designed using the LVDS (Low Voltage Differential Signaling) transmission scheme, and the jitter characteristics are analyzed by measuring the long distance transmission signal through the cable. In order to reduce the jitter, a pre-emphasis technique is applied to compensate the transmitting signal to be attenuated by long distance transmission, and the transmission characteristics were verified according to the distance.

본 논문은 수중 음향센서 데이터의 원거리 케이블 전송에 관한 연구 결과이다. LVDS(Low Voltage Differential Signaling) 전송 방식으로 설계된 데이터 송수신기의 케이블에 대한 원거리 전송 신호를 측정하고 지터 특성을 분석하였다. 지터 특성을 저감하기 위하여, 원거리 전송에 따라 감쇠될 송신 신호를 역 보상하는 고역 강조(pre-emphasis) 기법을 적용하였으며, 전송 거리에 따라 송신 특성을 검증하였다.
