Abstract
A coding method and apparatus are provided. The method includes: obtaining a to-be-coded sequence whose length is N, after an information bit is placed at an information bit position, wherein first preset bits are placed at shaping bit positions in a first position sequence, and shaping bit positions whose corresponding bits after polar coding belong to a same subcode of inner code belong to a same group; performing outer code coding on the to-be-coded sequence, to obtain a first outer code sequence whose length is N, based on which first outer code codeword bits corresponding to shaping bit position groups are obtained; obtaining a target outer code sequence based on the first outer code sequence and the first outer code codeword bits; and performing inner code coding on the target outer code sequence, to obtain and output a coded sequence. Probability amplitude shaping (PAS) coding latency can be reduced.
