Abstract

Such as disaster rescue in deep water, undersea exploration and monitering for environmental pollution, many applications require the acoustic communication for high data rate over underwater acoustic channel. As underwater channel is very complex and is time-varying, In this paper, The proposed OFDM system with synchronization errors and multipath delay spread is analyzed for high data rate and reliability and rubust service over UWA channels.

최근 심해 해난 구조 통신, 해저 탐사와 환경오염에 대한 모니터링과 같은 서비스에서 수중 음향 채널을 통한 데이터의 전송은 고속이 요구되고 있다. 그러나 수중 음향 채널은 매우 복잡하고 지속적인 시변 특성을 가지므로 양질의 통신 서비스를 제공하기란 쉽지 않다. 이러한 수중 음향 채널의 열악한 환경상에서 고속의 데이터 전송율과 신뢰성 그리고 강건성을 제공하기 위해서 다중경로 지연확산과 동기오류를 가지는 OFDM 시스템에 대한 성능개선 방안을 제안한다.
