Abstract

In an electronic apparatus, a soft decision likelihood value is generated and subject to a decoding process supporting a convolutional code; and a data series is interleaved, subjected to an error correction process, and decoded data is generated. A detecting unit, based on information concerning the position of a symbol for which an error has been corrected successfully by the error correction process, estimates whether an error occurs in a symbol for which the error correction process failed and detects the position of a symbol estimated to have an error. A setting unit sets based on the decoded data and information concerning the position of the symbol estimated to have an error, a correction value of the soft decision likelihood value. The electronic device interleaves the order of a correction value series of the soft decision likelihood value and feeds the resulting correction value series back to the decoding process.
