Abstract

In this paper, we propose a clipping method for LDPC coded FH BFSK system over partial-band jamming channel. We apply the erasure insertion technique, which had been studied much earlier, now to LDPC codes and discuss its performance degradation region. By using clipping technique, the performance degradation can be removed. Finally, we discuss the erasure insertion and clipping techniques for various jamming conditions.

본 논문에서는 부분 대역 재밍 채널에서 LDPC 부호화된 주파수 도약 BFSK 시스템의 신뢰도를 높이기 위한 소실 삽입 기법과 클리핑 기법을 제안하고 그들의 성능을 비교한다. 기존 항 재밍 대수 부호에 대해 널리 연구된 소실 삽입 기법을 LDPC 부호에 적용할 때의 성능 열화가 발생함을 확인하고, 클리핑 기법을 이용하여 이를 극복한다. 또한 다양한 PBJ 채널 상황에서 두 기법을 비교 분석한다.
