    Abstract: The embodiments of the present invention provide an encoding and decoding method and device. The encoding method includes: equally dividing input K-bit information into n blocks, where k1, k2, . . . , and kn are used to represent each block of information; combining a kith block of information with n−1 encoded code words Vi−1, Vi−2, . . . , and Vi−n+1 of ki−1th, ki−2th, . . . , and ki−n+1th blocks, to obtain a code word to be encoded, where when a sequence number of an encoded code word is smaller than or equal to 0, the encoded code word is history information; performing, by using an LDPC check matrix, encoding on the code word to be encoded, where a generated check bit and the kith block of information form an encoded code word Vi; and outputting encoded code words V1, V2, . . . , and Vn. The embodiments of the present invention are applied in encoding and decoding.

    Abstract translation: 本发明的实施例提供了一种编码和解码方法和装置。 编码方法包括:将输入K位信息等分成n个块,其中k1,k2,...。 。 。 ,和kn用于表示每个信息块; 将信息块与n-1个编码码字Vi-1,Vi-2组合。 。 。 ,第ki-1th,ki-2th的Vi-n + 1。 。 。 和第ki-n + 1个块,以获得要编码的码字,其中当编码码字的序列号小于或等于0时,编码码字是历史信息; 通过使用LDPC校验矩阵来对要编码的码字进行编码,其中产生的校验位和第一组信息块形成编码码字Vi; 并输出编码码字V1,V2。 。 。 ,和Vn。 本发明的实施例应用于编码和解码。
