공간적으로는 “Mt. Fuji” 결합(SFC) 저밀도 패리티 검사(LDPC) 코드는 블록 LDPC 코드 체인으로 구성됩니다. SFC-LDPC 코드와 원래의 SC(공간 결합) LDPC 코드 간의 차이점은 기본 블록 LDPC 코드의 코드 길이입니다. 체인 중간에 있는 블록 LDPC 코드의 코드 길이는 체인 끝 부분의 코드 길이보다 길다. SFC-LDPC 코드와 코드 길이 및 설계율이 동일한 SC-LDPC 코드에 비해 SFC-LDPC 코드의 에러 플로어 영역에서 비트 에러 확률이 낮은 것을 실험적으로 확인하였다. 본 글에서는 SFC-LDPC 코드의 가중치 분포를 계산하고 SFC-LDPC 코드의 낮은 비트 오류율의 원인을 설명하려고 합니다.

Abstract: Spatially “Mt. Fuji” coupled (SFC) low density parity check (LDPC) codes are constructed as a chain of block LDPC codes. A difference between the SFC-LDPC codes and the original spatially coupled (SC) LDPC codes is code lengths of the underlying block LDPC codes. The code length of the block LDPC code at the middle of the chain is larger than that at the end of the chain. It is experimentally confirmed that the bit error probability in the error floor region of the SFC-LDPC code is lower than that of the SC-LDPC code whose code length and design rate are the same as those of the SFC-LDPC code. In this letter, we calculate the weight distribution of the SFC-LDPC code and try to explain causes of the low bit error rates of the SFC-LDPC code.

AB - Spatially “Mt. Fuji” coupled (SFC) low density parity check (LDPC) codes are constructed as a chain of block LDPC codes. A difference between the SFC-LDPC codes and the original spatially coupled (SC) LDPC codes is code lengths of the underlying block LDPC codes. The code length of the block LDPC code at the middle of the chain is larger than that at the end of the chain. It is experimentally confirmed that the bit error probability in the error floor region of the SFC-LDPC code is lower than that of the SC-LDPC code whose code length and design rate are the same as those of the SFC-LDPC code.
