Abstract

In this paper, we study on symbol error rate(SER) performance of frequency domain decision feedback equalization for modelled underwater channel. Underwater channel is generated by Bellhop model. Simulation results show that proposed method is efficient for underwater acoustic communication.

본 논문에서는 수중무선통신에서 다중경로에 의해 발생하는 심볼간 간섭을 제거하기 위한 방법으로, 단일반송파 전송방식에 주파수-시간 영역 등화 기법을 결합한 주파수영역 결정궤환 등화기법에 대한 성능을 평가한다. 수중채널 모델링은 벨홉모델을 이용하였으며, 모의실험을 통해, 제안한 기법이 심볼간 간섭에 의한 신호왜곡 문제에 효율적으로 대처할 수 있는 대처할 수 있는 전송방식임을 보였다.
