Title:
CHANNEL INTERLEAVING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/001449
Kind Code:
A1
Abstract:
Disclosed is a channel interleaving method for a polar code. The method comprises: determining a matrix with M_r rows and M_c columns used for interleaving, wherein a column serial number of the matrix is expressed as: [0, 1…, ic, …M_c-1], with ic being greater than or equal to 0 and less than or equal to M_c-1, and a row serial number of the matrix is expressed as: [0, 1…, ir, …M_r-1], with ir being greater than or equal to 0 and less than or equal to M_r-1; writing, into the matrix, a bit to be interleaved; permutating the matrix that the bit to be interleaved is written into, according to a permutation pattern of the column serial number and/or a permutation pattern of the row serial number, wherein the permutation pattern of the column serial number is expressed as: [Pc(0), Pc(1)…, Pc(ic), …Pc(M_c-1)], with Pc(ic) being obtained by performing pruned bit reverse (PBR) mapping on the column serial number ic, and the permutation pattern of the row serial number is expressed as: [Pr(0), Pr(1)…, Pr(ir), …Pr(M_r-1)], with Pr(ir) being obtained by performing pruned bit reverse(PBR) mapping on the row serial number ir; and reading out the interleaved bit from the permutated matrix.
