Encoding method, encoder and data transmission system

Abstract

An encoding method, applied to the field of encoding technologies, may be used for reducing the delay and reducing the decoding memory, and includes: obtaining a data signal including a plurality of information bits; and performing encoding process on the data signal to obtain an encoded signal. An encoding block in the encoded signal includes a first encoding sub-block and at least one second encoding sub-block. The first encoding sub-block includes first component codewords and second component codewords, and all information bits constitute an information bit matrix. Each second encoding sub-block includes a first check matrix, which includes first check bit sets each determined based on bits of a first bit matrix with same side lengths, and the first check bit set and the bits of the first bit matrix constitute a third component codeword.
