Claim:
1. A data block interleaving method for a transmitter in communication equipment, wherein the method includes the following steps: obtaining by the transmitter an original permutation matrix before the permutation matrix is interleaved; interleaving by the transmitter the original permutation matrix, wherein, the relationship between a position coordinate (i, j) of any one bit in the original permutation matrix and a position coordinate (I, J) of the bit in the interleaved permutation matrix is: if I=0, then if I≠0, then where, i(I, J) is a row coordinate in the original permutation matrix of the bit that has a position coordinate (I, J) in the interleaved permutation matrix, j(I, J) is a column coordinate in the original permutation matrix of the bit that has a position coordinate (I, J) in the interleaved permutation matrix, i=0, 1, . . . , m−1, j=0, 1, . . . , n−1, I=0, 1, . . . , m−1, J=0, 1, . . . , n−1, m and n are the number of columns and the number of rows of the original permutation matrix respectively, mod indicates a modulo operation, and m where, m and ñ outputting by the transmitter the interleaved permutation matrix.
