Disclosed is an OFDM receiving apparatus for receiving a signal that has sustained inter-symbol interference owing to a delayed wave that exceeds a guard interval, eliminating at least inter-symbol interference from the receive signal and applying demodulation and decoding processing to the receive signal from which interference has been eliminated. A combination of number of iterations of the equalization processing for eliminating interference from a receive signal and for demodulating and decoding the receive signal and number of iterations for repeating the decoding in the decoding processing is changed over based upon the state of the propagation path, e.g., the SIR, which is the ratio of desired signal power to interference power.
