ABSTRACT:
The invention relates arranging information bits in an information matrix; encoding rows of the information matrix for generating a base code matrix; generating a parity check row for the base code matrix to obtain an extended code matrix; shifting predetermined rows of the extended code matrix with respect to a preceding row in a predetermined way and generating a following parity check row for obtaining a following extended code matrix in such a way that there are more than two parity check rows in the following extended code matrix; and derotating the rows of the following extended code matrix for generating a multiple parity code matrix.
