PROBLEM TO BE SOLVED: To execute an error correction process in a next generation terrestrial digital broadcast transmission system without substantially increasing an amount of memory use.SOLUTION: A transmission device 1 according to the present invention includes LDPC encoding units 15a/15b for applying an LDPC encoding process to transmission data to generate an LDPC code. The LDPC encoding units 15a/15b are configured to generate a check matrix Hof the LDPC code from an original check matrix H by using a prescribed mathematical expression and initial value.SELECTED DRAWING: Figure 2 【課題】メモリ使用量を著しく増加させることなく次世代の地上デジタル放送伝送方式における誤り訂正処理を実現する。【解決手段】本発明に係る送信装置１は、送信データに対してＬＤＰＣ符号化処理を施してＬＤＰＣ符号を生成するＬＤＰＣ符号化部１５ａ／１５ｂを具備しており、ＬＤＰＣ符号化部１５ａ／１５ｂは、所定の数式及び初期値を用いて、元となる検査行列Ｈから、ＬＤＰＣ符号の検査行列ＨＣを生成するように構成されている。【選択図】図２
