摘要： In the present application, there is provided a decoding apparatus for decoding low density parity check codes, including: a plurality of storage sections configured to store logarithmic likelihood ratios or logarithmic posteriori probability ratios for one codeword into addresses thereof which are independent of each other thereamong; and a readout section configured to simultaneously read out, from among the logarithmic likelihood ratios or logarithmic posteriori probability ratios for the one codeword stored in the storage sections, a plurality of ones of the logarithmic likelihood ratios or logarithmic posteriori probability ratios which correspond to non-zero value elements in a predetermined one row of the check matrix used in a coding process of the low density parity check codes.
