Encoding device for performing serial concatenated coding

摘要

The present invention is particularly applied to serial concatenated coding and serial concatenated trellis coded modulation. In second encoding 107 , which is inner coding, a sequence that is not encoded or that is encoded so as to produce a finite impulse response and a sequence that is encoded so as to produce an infinite impulse response are output. In interleaving 106 before the second encoding 107 , the sequences are permuted so as not to be mixed with each other.
