A decoding apparatus for performing decoding processing of encoded data by using non-binary LDPC codes, includes: a logarithmic Fourier transform processing section, a variable node processing section, an edge coefficient processing section, and a check node processing section, wherein the logarithmic Fourier transform processing section performs Fourier transform processing and logarithmization processing on a probability vector of a symbol of an encoded frame data to output an initial value of logarithmic Fourier domain probability vector, and the variable node processing section, the edge coefficient processing section, and the check node processing section perform iteration processing by using a logarithmic Fourier domain probability vector. |
