POLAR CODING BASED ON MOTHER CODE HAVING A RELIABILITY SEQUENCE DERIVED FROM THE RELIABILITY SEQUENCE OF A MAXIMUM LENGTH MOTHER CODE

摘要

Embodiments of this application disclose a polar coding method, apparatus, and device, so as to reduce storage overheads of a system. The method includes: obtaining a maximum mother code sequence, where the maximum mother code sequence is characterized in that, if a first sequence whose code length is Z is read from the maximum mother code sequence, ordering, in the first sequence, of Z sequence numbers included in the first sequence is the same as ordering, in the maximum mother code sequence, of the Z sequence numbers, where Z=2 z , z‰¤n, and z is a positive integer; and performing polar coding by using the maximum mother code sequence.
