METHOD AND APPARATUS FOR DECODING OF PRODUCT CODES
摘要
PURPOSE: A decoding method of a product code and an apparatus thereof are provided to make decoding result of very low error rate by reducing the complexity of calculation during a process of decoding the codeword matrix of the product code. CONSTITUTION: A decoding device selects soft-decision information of a horizontal code word as one soft-decision information about a decoding-failed horizontal code word. The soft-decision information is already calculated from the channel receiving information. The decoding device extracts another soft-decision information about horizontal code words using hard decision information of horizontal code words which are successfully decoded and the soft-decision information of other horizontal code words which are decoding-failed. The decoding device re-decodes the horizontal code words by adding two soft-decision information on the horizontal code words. The decoding device eliminates the matrix corresponding to the decoding success from a second expansion parity check matrix.
