Abstract

AThis paper measured real sea area for performance analysis according to distance from west sea and south sea of Korea. The performance of the underwater OFDM system was analyzed by comparing the performance of the West and South Seas by adjusting the number of data repetitive transmissions and the pilot symbol placement interval parameters based on the real-sea data measured from the distance and Data rate of the West and South Sea vessels. In conclusion, when comparing the performance of the South Sea at the Data rate and distance, the BER performance of the South Sea was similar at the 5 km South Sea and 1 km West Sea under the same conditions. Placement interval of pilot symbol at 10 km of South Sea and 3 km of West Sea is (𝚫f, 𝚫t) = (6, 3) and the number of times the PRB is (Rf, Rt) = (2, 1) repeated. We confirmed that we can send high data over long distances in the South Sea.

본 논문은 대한민국 서해와 남해에서의 거리에 따른 성능분석을 위해 실해역 측정을 했다. 서해와 남해 선박의 거리와 전송율 관점에서 측정된 실해역 데이터를 기반으로 데이터 반복 전송 횟수와 파일럿 심볼 배치 간격 파라미터를 조절하여 서해와 남해 성능 비교를 통해 수중OFDM 시스템을 성능을 분석하였다. 결론으로는 전송율과 거리에서 남해의 성능을 비교했을 때 파라미터가 같은 조건에서 남해 5km, 서해 1km 거리에서 BER성능이 남해가 성능이 비슷하였으며, 남해 10km,서해 3km에서 파일럿 심볼의 배치간격을 (𝚫f, 𝚫t) = (6, 3)의 심볼과 PRB가 반복되는 (Rf, Rt) = (2, 1)에서 남해는 1078.92bit/s 서해는 1384.57bit/s으로 전송율관점에서도 남해에서 장거리에서 높은 데이터를 보낼 수 있는걸 확인하였다
