    • In a mobile communication system including a transmitter and a receiver, an LDPC code is generated by encoding received information data such that a fifth partial matrix obtained by combining a second partial matrix having even-numbered columns of a first partial matrix corresponding to the information data with a fourth partial matrix having odd-numbered columns of a third partial matrix corresponding to a parity, and an eighth partial matrix obtained by combining a sixth partial matrix having odd-numbered columns of the first partial matrix with a seventh partial matrix having even-numbered columns of the third partial matrix correspond to a ninth partial matrix obtained by exclusive-ORing the first partial matrix and the third partial matrix and a parity check matrix having a predetermined rank in a binary field. A space-time LDPC code is generated by spatial-mapping the LDPC code according to a predetermined spatial mapping scheme.
    • 在包括发射机和接收机的移动通信系统中,通过编码所接收的信息数据来生成LDPC码,使得通过组合具有与信息数据相对应的第一部分矩阵的具有偶数列的第二部分矩阵而获得的第五部分矩阵 第四部分矩阵具有对应于奇偶校验的第三部分矩阵的奇数列,以及通过将具有第一部分矩阵的奇数列的第六部分矩阵与具有偶数列的第七部分矩阵组合而获得的第八部分矩阵, 第三部分矩阵的编号列对应于通过对二进制字段中的第一部分矩阵和第三部分矩阵进行异或运算而获得的第九部分矩阵和具有预定等级的奇偶校验矩阵。 通过根据预定的空间映射方案对LDPC码进行空间映射来生成时空LDPC码。
