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 k, k, . . . , and kare used to represent each block of information; combining a kiblock of information with n−1 encoded code words V, V, . . . , and Vof k, k, . . . , and kblocks, 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 kblock of information form an encoded code word Vi; and outputting encoded code words V, V, . . . , and V. The embodiments of the present invention are applied in encoding and decoding.
