Abstract
According to one embodiment, an encoder/decoder apparatus includes an encoder module, a decoder module, and a transposing module. The encoder module is configured to generate a Hamming code from the input data, in accordance with a check matrix having a specific regularity. The decoder module is configured to detect an error position in the output data composed of the Hamming code, in accordance with the check matrix. The transposing module is configured to perform a transposing process of transposing some of the columns of the check matrix, while maintaining the regularity of the check matrix, and to change the error position in accordance with the transposing process, during the decoding process.
