Abstract

This paper proposes an adequate UWA (Underwater Acoustic) communication system of underwater communication network in the Yellow Sea. UWA channel is obtained from Bellhop ray tracing method with Yellow Sea environments. Based on this channel, communication parameters for CDMA (Code Division Multiple Access) and SC-FDM (Single Carrier-Frequency Division Multiplexing) using diversity techniques are calculated. In order to prove the proposed methods, BER (Bit Error Rate) and data rate are obtained using computer simulations and the adequate communication system for long rms delay spread and low Eb/No environments is proposed from the simulation.

본 논문은 서해의 수중음향 통신 네트워크의 물리계층에 적합한 수중음향통신 시스템을 제안한다. 서해정점의 해양 관측정보와 Bellhop 음선 추적프로그램을 이용하여 서해정점의 수중 채널 모델을 구하고 이 수중 채널 모델을 이용하여 통신 변수들을 산출하고 다이버시티 기법이 응용된 CDMA(Code Division Multiple Access)와 SC-FDM (Single Carrier-Frequency Division Multiplexing) 전송방식을 이용한 음향 통신시스템을 설계한다. 설계된 통신시스템의 성능을 검증하기 위해 여러 통신환경에 대한 비트 오류율과 데이터 전송률을 연산하고 이로부터 서해안에서 긴 지연시간을 가지는 수중 채널과 낮은 Eb/No에서 사용가능한 수중 음향통신 기법을 제안한다.
