Abstract
A decoder for decoding an encoded word X having N bits as an encoded signal that was encoded by an encoder from an ex-code word Y having M bits as a signal before being encoded by the encoder, includes (a) a correlation matrix computation part which makes computation of the encoded word X with a correlation matrix W defined by N rows and M columns, to output a computation result having 1 row and M columns and thereby M components, (b) a judgment part which judges each component in the computation result, and (c) an ex-code word output part which outputs a result of judgment carried out in the judgment part, as a recovered ex-code word corresponding to the ex-code word Y.
