Patent granted for ldpc code creation and error correction
A recently granted patent (Publication Number: US11916667B1) discloses a method for creating a low-density parity-check code (LDPC) using an encoder and a decoder. The method involves positioning coded bits, including information bits, constant bits, and check bits, in a three-dimensional matrix and calculating the check bits to ensure specific modulo-2 sums across ranks, columns, and rows. The decoder then utilizes the LDPC to perform error correction in a communication system. The patent also details the arrangement of basic bits in the matrix, the calculation of check bits along paths through the matrix, and the inclusion of additional check bits for error correction.
Furthermore, the patent extends the method to a four-dimensional matrix, where coded bits are positioned in files, ranks, columns, and rows. The check bits are calculated to maintain modulo-2 sums across various combinations of these dimensions. The decoder continues to perform error correction based on the LDPC. The patent also covers the arrangement of basic bits in the four-dimensional matrix, the calculation of check bits along paths, and the inclusion of additional check bits for error correction. The system described in the patent includes an encoder, a decoder, and additional components like modulators and antennas for converting and transmitting the LDPC-encoded information. Overall, the patent provides a detailed method and system for creating LDPC codes and performing error correction in communication systems using multi-dimensional matrices.
