In an OFDM receiver, one of a plurality of antennas is selected based on a ratio X of two moving average integration values (first moving average integration value and second moving average integration value) that are calculated from a non-delay symbol and a delay symbol. It could be said that the second moving average integration value represents excessive false information (that is, whether the state of the transmission line is good). Accordingly, determination of the ratio X between the second moving average integration value and the first moving average integration value and selection of one of the plurality of antennas based on the ratio X enables judgment on whether the state of the transmission line is good even during a period other than a guard interval period Tg, that is, during an effective symbol period Tu. |
