NODE INFORMATION STORAGE METHOD AND SYSTEM FOR A LOW-DENSITY PARITY-CHECK DECODER

摘要

A receiver to receive a signal associated with a low-density parity-check (LDPC) code. The receiver includes a memory device, an address generator, and an LDPC decoder. The LDPC decoder includes a row designator and a position designator. The memory device stores data related to an LDPC decoding process. The address generator generates an access address to the stored data. The LDPC decoder performs the LDPC decoding process. The row designator designates a row from a parity-check matrix as a parent row and designates a plurality of corresponding rows from the parity-check matrix as child rows. The position designator designates an original position order of each parent non-zero element of 10 the parent row according to an actual position order of each parent non-zero element in the parent row. The actual position order includes a numerical order of the parent non-zero elements.
