Abstract
Methods and apparatus for constructing a parity check matrix for use in a low-density parity check (LDPC) coding scheme are provided. The apparatus includes at least one index generator for generating row indexes of '1's, which indicate row positions of the '1's in each column of the parity check matrix, wherein the index generator is implemented by a modular shift register generator that generates a row index of a “1” at each clock.
