POLAR CODE RATE MATCHING METHOD AND DEVICE Russian patent published in 2019 - IPC H03M13/27 H04L1/00 

FIELD: physics.

SUBSTANCE: group of inventions relates to the field of coding and can be used to coordinate the speed of the polar code. Method performed by the speed negotiation device comprises the steps of: perform bit interleaving in reverse order over the polar code, display the i input bit in Π(i +Δ mod N) output bit, where i = 0, 1, …, and N-1, Δ is the offset, Π(i) is obtained from BRO_M(j), while BRO_M(j) indicates that the operation of inverting the order of the bits is performed on the index j, and M is a positive integer indicating the size of the BRO_M(j); and determine, on the basis of the interleaved bits, the output sequence with a consistent rate.

EFFECT: technical result is to reduce the frame error rate (FER), which improves the HARQ efficiency and ensures the reliability of data transmission.
