METHOD AND APPARATUS FOR ENCODING AND DECODING OF LOW DENSITY PARITY CHECK CODES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240048158 titled 'METHOD AND APPARATUS FOR ENCODING AND DECODING OF LOW DENSITY PARITY CHECK CODES

Simplified Explanation

The abstract describes an encoding apparatus that utilizes a low density parity check (LDPC) encoder to perform LDPC encoding on input bits. This encoding process is based on a parity-check matrix and generates an LDPC codeword consisting of 64,800 bits. The parity-check matrix consists of an information word sub-matrix and a parity sub-matrix. The information word sub-matrix is composed of multiple column blocks, each containing 360 columns. The positions of value one in every 360th column are represented by various tables that define the parity-check matrix and the information word sub-matrix.

  • The encoding apparatus includes a LDPC encoder that performs LDPC encoding on input bits.
  • The LDPC encoding is based on a parity-check matrix.
  • The LDPC codeword generated by the encoder consists of 64,800 bits.
  • The parity-check matrix comprises an information word sub-matrix and a parity sub-matrix.
  • The information word sub-matrix is formed by a group of column blocks, each containing 360 columns.
  • Various tables are used to define the positions of value one in every 360th column of the parity-check matrix and the information word sub-matrix.

Potential Applications:

  • Communication systems that require error correction coding.
  • Data storage systems that utilize LDPC encoding.
  • Wireless communication technologies that benefit from LDPC encoding.

Problems Solved by this Technology:

  • Error correction in communication systems.
  • Improved reliability and accuracy of data transmission.
  • Efficient storage and retrieval of data in storage systems.

Benefits of this Technology:

  • Enhanced error correction capabilities.
  • Higher reliability and accuracy in data transmission.
  • Improved efficiency in data storage and retrieval.


Original Abstract Submitted
