Abstract

A decoding device and decoding method for carrying out repetitive decoding appropriate times so as to ensure a desired transmission quality and to reduce operation delay. A turbo decoder (301) repeats an error-correction decoding of an inputted code sequence. An error detector (302) decodes an error detection code included in the result of the error correction decoding and detects an error, if any, remaining in the result of the decoding by the turbo decoder (301). A repetition controller (303) orders a repetitive decoding until the repetitive decoding is repeated repetition restriction times and until the error detector (302) detects no error in the result of the decoding.

Description

technical field

[0001] The present invention relates to a decoding device and a decoding method for repeatedly decoding a code sequence obtained by performing error detection coding and error correction coding on information bits, and particularly relates to a code sequence subjected to error correction coding by a turbo code A decoding device and a decoding method for decoding. Background technique

[0002] In the field of mobile communications, techniques for detecting and correcting errors occurring on channels due to noise or the like are being actively studied. In digital communication in particular, error control techniques for correcting errors that have not been fully recovered by signal processing such as equalization or diversity are widely used. This error control technique is broadly classified into automatic repeat request (ARQ; Automatic Repeat reQuest) and forward error correction (FEC; Forward Error Correction). ARQ is a technology...
