FIELD: communication.
SUBSTANCE: information bit sequence and length M of a target polar code are obtained, and, when the length M of the target code satisfies a given condition, a polar code with the first length N1 is used for encoding the information bit sequence and outputting the first encoded bit sequence, where N1 is less than or equal to M, and N1 is an integer degree of 2, and at least some bits are repeated in the first encoded bit sequence to obtain the first target polar code with the length M, or, when the length M of the target code does not satisfy the given condition, a polar code with the second length N2 is used for encoding the information bit sequence to output the second encoded bit sequence, where N2 is greater than or equal to M, and N2 is an integer degree of 2, and the second encoded bit sequence is shortened or chipped out to obtain the second target polar code with the length M.
EFFECT: increase in the reliability of data transmission.
