<p>Disclosed is a wireless receiver device capable of avoiding deterioration in reception quality in an SFN environment, even when a delayed wave is present that exceeds the guard interval. In the device, an OFDM receiver (100) receives a wireless signal via a network that uses a single frequency. An antenna directivity control unit (122) forms directivity when the signal is received. An OFDM receiver unit (120) measures reception level and reception quality. A transmitter station information database (140) associates transmitter station location information with a transmitter station and stores same. A determination unit (121) selects a transmitter station and changes directivity formed by the antenna directivity control unit (122) for each such selection on the basis of the reception level, the reception quality, the present location information of the OFDM receiver (100), and the transmitter station location information that is stored in the transmitter station information database (140).</p> |
