Parity check bits (403) are calculated for the information received (401). A base model matrix (403) is defined for the largest code length of each code rate. The set of shifts {p(i,j)} in the base model matrix (403) are used to determine the shift sizes for all other code lengths of the same code rate. Shift sizes {p(f, i, j)} for a code size corresponding to expansion factor zf are derived from {p(i,j)} by scaling p(i,j) proportionally, and a model matrix by {p(f,i,j)} is used to determine the parity-check bits (403)for the f-th code. ® KIPO & WIPO 2007
