Disclosed are a turbo decoding apparatus and method for decoding a turbo-encoded signal by repeating element decoding. The apparatus includes a plurality of element decoders for applying element decoding, e.g., MAP decoding, in parallel to respective ones of a plurality of divided signals to be decoded, and an interleaver/deinterleaver for interleaving or deinterleaving a plurality of results of element decoding collectively. Each element decoder applies element decoding to a respective one of the divided signals, and the interleaver/deinterleaver alternately interleaves and deinterleaves a plurality of results of element decoding collectively. Turbo decoding is carried out by repeating these operations a prescribed number of times.
