초록

본 논문에서는 LDPC 코드 대신 LDGM 코드를 이용한 랩터(Raptor) 코드 구성을 제안한다. 그리고 실험을 통하여 두 코드 성능을 비교한다. 시뮬레이션으로 두 코드 성능을 비교한 결과 LDGM 코드를 이용한 랩터 코드가 LDPC 코드를 이용한 랩터 코드보다 성능은 좋지 않았지만 인코딩 복잡도는 더 간단한 것으로 확인되었다.

In this paper, we propose the construction of Raptor code using LDGM code instead of LDPC code as precode. To see their merits, the simulations are done. The results show that the performance in case of using LDGM code is worse than that of using LDPC code as precode, and the complexity of encoding LDGM code is lower than that of LDPC.
