Abstract:
1. An encoder comprising: a coding section that generates coded sequence s that satisfies equation 1-1, equation 1-2 and equation 1-3 for information bit sequence u; and a setting section that sets a y-th puncturing pattern which corresponds to the number of columns z ranging from z×y+1 columns (y is an integer between 0 and (n wherein, in the coded sequence s made up of z×n [1] where H is a parity check matrix of an low density parity check code of (z×mb) rows and (z×nb) columns configured by arranging submatrixes of z rows and z columns in nib rows and nb columns, G is a generator matrix holding a relationship of equation 1-1 with parity check matrix H of the low density parity check code and the coded sequence s is a coded sequence made up of z×nb bits.
