Abstract
Embodiments of this application provide a coding and modulation method, a demodulation and decoding method, an apparatus, and a device. The coding and modulation method includes obtaining K to-be-encoded bits and a modulation scheme, and coding the K to-be-encoded bits, based on M bit levels of the modulation scheme, to obtain M' code blocks, where M′<M, a code length of an icode block is N, N=M*N, Mis a quantity of bit levels corresponding to the icode block, N is a symbol block length, and 1≤i≤M′. The disclosed method further includes modulating the M′ code blocks, according to a mapping relationship between the M′ code blocks and the M bit levels, to obtain and output a modulated symbol sequence, where a code block whose code length is M*N corresponds to Mbit levels in the mapping relationship.
