Title: ENCODING METHOD, DECODING METHOD, ENCODING DEVICE, AND DECODING DEVICE
Abstract:
Disclosed are an encoding method, a decoding method, an encoding device, and a decoding device. The encoding method comprises: determining the size of a shift matrix according to the length of an information sequence and the length of an identification sequence; constructing a check matrix according to the size of the shift matrix and a basis matrix; and carrying out low density parity check (LDPC) encoding on the information sequence and the identification sequence based on the check matrix, wherein the identification sequence is a non-all-zero sequence. By means of embodiments of the present application, the function of the LDPC check matrix can be extended, and the identification degree of encoding codeword is improved.
