A decoding apparatus includes a first decoder and a second decoder as a decoding processor for performing iterative decoding on received data, a hard decision section for calculating hard decision results based on logarithmic likelihood ratios L1 and L2 from the first and second decoders, and a stop determination section performing stop determination on whether or not to stop the iterative decoding on the received data based on the result of the hard decision section. The decoding apparatus completes one-time iterative decoding by executing decoding process in each of the first and second decoders. The stop determination section executes stop determination at the timings of completion of the decoding process in the first decoder and completion of the decoding process in the second decoder.
