Abstract
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 r[k] and r[k]. Based on the sampled data, a level detector finds an interference evaluation value C[l] for each OFDM symbol by counting the number of times one of the data r[k]and r[k] is clipped to the maximum output range of the ADC. When the interference evaluation value C[l] is greater than or equal to an interference decision value th, a weighting control section corrects a soft-decision value wby multiplying it by a weighting factor γso as to decrease contribution of an error correction code to decoding.
