Abstract
To shorten a time required for a decoding process of a turbo codes without an increase in an operating frequency of the decoder by making concurrent operations of two soft-output decoders possible, the present invention provides soft-output decoders () for outputting a reliability information likelihood, interleavers () for interleaving transmission information to supply to the soft-output decoder, interleaver () for interleaving a reliability information likelihood to supply to the soft-output decoder, and deinterleavers () for deinterleaving the reliability information likelihood to supply to the soft-output decoder. Since these elements are constructed as two circuits having the same configuration and two soft-output decoders are operated concurrently in an iterative decoding process for a second time et seq. in the iterative decoding process of the turbo codes, a processing time required for the decoding process for the second time et seq. can be reduced by half.
