<p>A structured parity-check matrix H is proposed, wherein H is an expansion of a base matrix H b . Base matrix H b comprises a section H b1 and a section H b2 . Section H b2 comprises column h b having weight w h >=3 and H ' b2 having a dual-diagonal structure with matrix elements at row i, column j equal to 1 for i=j, 1 for i=j +1 , and 0 elsewhere. The 1's of h b and H b1 are arranged such that m b lq groups can be formed so that the q rows of H b within each group do not intersect. Further more, the rows of base matrix H b can be permuted such that every two consecutive rows do not intersect.</p> |
