Classification: CPC H | IPC H

Claim 7:
8. A method for creating a low-density parity-check code (LDPC) using an encoder and a decoder by:
positioning, using the encoder, coded bits comprising information bits, 0 or more constant bits, and check bits in a four-dimensional matrix having files, ranks, columns, and rows; and
calculating, using the encoder, the check bits such that a modulo-2 sum across the files of all combinations of ranks, columns, and rows, across the ranks of all combinations of files, columns, and rows, across the columns of all combinations of files, ranks, and rows, and across the rows of all combinations of files, ranks, and columns is 0; and
using the decoder, and based at least on the LDPC, performing error correction in a communication system.
