METHOD FOR SPEED MATCHING, ENCODING DEVICE AND COMMUNICATION DEVICE Russian patent published in 2021 - IPC H04B7/26 H04L1/00 

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.
