| 摘要 | Disclosed are a method and an apparatus for generating a codeword, and a method and an apparatus for recovering a codeword. An encoder calculates the number of punctured symbol nodes among symbol nodes included in a codeword, punctures symbol nodes located at even or odd number positions among the symbol nodes included in the codeword, calculates the number of symbol nodes which need to be additionally punctured on the basis of the calculated number of the symbol nodes to be punctured, classifies the symbol nodes, which need to be additionally punctured, into one or more punctured node groups on the basis of the calculated number of symbol nodes which need to be punctured, determines the locations on the codeword where the one or more punctured node groups are to be arranged, and punctures the symbol nodes included in the codeword which belong to the punctured node groups according to the determined locations. A transmission unit transmits the codeword. | ||||||
