Abstract
A transmission apparatus includes, a receiving circuit that receives a reception signal indicating a coded bit string, a decoding circuit that decodes and corrects the bit string by using a spatially-coupled low density parity check code constituted by arranging element matrixes stepwise in a diagonal direction, a parity check matrix of the spatially-coupled low density parity check code including at least one element matrix having at least one of a number of rows and a number of columns different from a number of rows and a number of columns of other element matrixes when each sparse matrix constituting the parity check matrix is regarded as an element matrix, and outputs the corrected bit string.
