Abstract: An iterative receiving device and an iterative decoding device are provided to improve an iterative reception, an iterative decoding performance, and a collecting speed by using an optimum detector like a MAP(Maximum A Posteriori) detector as an inner detector. An inner detector(201) detects a receiving signal. An outer decoder(203) decodes the receiving signal detected by the inner detector. An impurity addition device(205) adds impurity to an output signal of the outer decoder. An interleaver(204) performs interleaving between the inner detector and the outer decoder. A de-interleaver(202) performs de-interleaving between the inner detector and the outer decoder. The inner detector is an SC-MMSE(Soft interference Cancellation with Minimum Mean Squared Error) or a MAP detector.
