Abstract
The present invention provides channel interleaving method of a polar (Polar) code. The method includes: determining an M_-row and M_-column matrix used for interleaving, and permutating, based on permutation patterns of the column sequence numbers and/or permutation patterns of the row sequence numbers, the matrix into which the to-be-interleaved bits are written. The permutation patterns of the column sequence numbers are represented by: [P(0), P(1), . . . , P(i), . . . , P(M_−1)]. P(i) is obtained by performing pruned bit reverse (PBR, pruned bit reverse)-based mapping on the column sequence number i. The permutation patterns of the row sequence numbers are represented by: [P(0), P(1), . . . , P(i), . . . , P(M_−1)]. P(i) is obtained by performing pruned bit reverse (PBR, pruned bit reverse)-based mapping on the row sequence number i; and reading interleaved bits from the permutated matrix.
