Abstract

In this paper, we evaluate the communication performance of convolutional code with block interleaving in a frequency-selective channel. Block interleaving is a technique for spreading and rearranging digital data streams. A block interleaving technique is applied to improve the performance by dispersing the concentration of burst errors in a frequency-selective channel. As a result of evaluating the performance of the convolutional code with block interleaving in the water tank experiment, There was no difference in the performance of convolutional codes using block interleaving in a frequency-selective channel. However, in the frequency-selective channel, the convolutional code with block interleaving has a gain of 2 dB, and it is confirmed that the underwater acoustic communication performance is improved.

본 논문은 수중 주파수 선택적 채널에서 블록 인터리빙 기법을 적용한 길쌈부호기법의 통신성능을 평가하였다. 블록 인터리빙은 디지털 데이터 열을 확산 분산하고 재배치하는 기법으로 주파수 선택적 채널에서 연집오류(burst error)의 집중을 분산시켜 성능을 향상하게 시키는 기법으로 블록 인터리빙 기법이 적용되고 있다. 수조 실험에서 블록 인터리빙이 적용된 길쌈부호의 성능을 평가한 결과 주파수 비 선택적 채널에서 블록 인터리빙을 적용한 길쌈부호의 성능의 차이가 없었다. 하지만 주파수 선택적 채널에서는 블록 인터리빙이 적용된 길쌈부호가 길쌈부호보다 2 dB 이득이 발생하였으며, 이로 인해 수중 음향 통신 성능향상에 기여함을 확인하였다.
