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 18482517 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. The LDPC encoder generates an LDPC codeword consisting of 64,800 bits. The parity-check matrix used in the encoding process includes 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 (1) present in every 360th column are defined by various tables.
- The encoding apparatus utilizes a low density parity check (LDPC) encoder for encoding input bits.

Original Abstract Submitted
An encoding apparatus is provided. The encoding includes a low density parity check (LDPC) encoder which performs LDPC encoding on input bits based on a parity-check matrix to generate an LDPC codeword formed of 64,800 bits, in which the parity-check matrix includes an information word sub-matrix and a parity sub-matrix, the information word sub-matrix is formed of a group of a plurality of column blocks each including 360 columns, and the parity-check matrix and the information word sub-matrix are defined by various tables which represent positions of value one (1) present in every 360-th column.
