A reception apparatus, method and a program using the reception method are provided to prevent degradation of reception quality due to interference. In a reception apparatus, an ADC samples data rIq[k] and rQq[k]. Based on the sampled data, a level detector finds an interference evaluation value Cc[l] for each OFDM symbol by counting the number of times one of the data rIq[k]q and rQq[kq] is clipped to the maximum output range of the ADC. When the interference evaluation value Cc[l] is greater than or equal to an interference decision value thc, a weighting control section corrects a soft-decision value wl,m,n by multiplying it by a weighting factor γc so as to decrease contribution of an error correction code to decoding.
