Abstract:
(EN) A method for encoding a quasi-cyclic low-density parity-check (LDPC) code according to an embodiment of the present invention may comprise the steps of: generating a multi-edge LDPC code matrix including a high rate code matrix and a single parity check code matrix; and encoding a signal by using the multi-edge LDPC code matrix, wherein the single parity check code matrix includes a first matrix having a non-row-orthogonal structure matrix and a second matrix having a pure row-orthogonal structure, which are concatenated.
(FR) La présente invention concerne, dans un mode de réalisation, un procédé de codage d'un code à contrôle de parité à faible densité (LDPC) quasi-cyclique pouvant comprendre les étapes suivantes: la génération d'une matrice de code LDPC multi-bord comprenant une matrice de code haut débit et une matrice de code à contrôle de parité unique; et le codage d'un signal à l'aide de la matrice de code LDPC multi-bord, la matrice de code à contrôle de parité unique comprenant une première matrice ayant une matrice à structure non orthogonale en rangée et une seconde matrice ayant une structure orthogonale en rangée pure, qui sont concaténées.
(KO) 본 발명의 일 실시예에 따른 LDPC (Quasi-Cyclic Low-Density Parity-Check) 코드의 인코딩 방법은 고 율 코드(high rate code) 행렬과 단일 패리티 체크 코드 행렬로 구성되는 다 엣지(multi edge) LDPC 코드 행렬을 생성하는 단계; 및 상기 다 엣지 LDPC 코드 행렬을 이용하여 신호를 인코딩 하는 단계를 포함하되, 상기 단일 패리티 체크 코드 행렬은 비 행-직교(non row-orthogonal) 구조 행렬로 구성되는 제 1 행렬과 순 행-직교(pure row-orthogonal) 구조로 구성되는 제 2 행렬이 연접하여 구성될 수 있다.
