Parity check matrix storing method, block LDPC coding method, and apparatus using parity check matrix storing method
摘要：
The present invention relates to a low density parity check (LDPC) encoding method and an apparatus thereof. In the LDPC encoding method, a matrix multiplication corresponding to ET−1 and T−1 is eliminated according to a structural characteristic in an encoding process. Accordingly, shift weights that are not −1 among shift weights corresponding to partial blocks A, B, and C of a parity check matrix are used to perform an encoding operation, and a cyclic shift operation of an information unit block is performed in parallel so that a first parity block and a second parity block may be simultaneously generated.
摘要（中）：

本发明涉及一种低密度奇偶校验（LDPC）编码方法及其装置。 在LDPC编码方法中，根据编码处理中的结构特征，消除对应于ET-1和T-1的矩阵乘法。 因此，使用对应于奇偶校验矩阵的部分块A，B和C的移位权重之中不为-1的移动权重进行编码操作，并行执行信息单元块的循环移位操作 可以同时生成第一奇偶校验块和第二奇偶校验块。
