A derivation unit derives SNRs corresponding respectively to two repeated OFDM symbols having the same content. The derivation unit generates, from the derived SNRs, a control signal necessary for deriving weighting factors and then outputs this control signal as a combined control signal. An FFT unit performs FFT on a signal combined by a delay symbol synthesizing unit. An equalization unit performs equalization processing on subcarrier signals inputted from the FFT unit. While associating two weighting factors with OFDM symbols of the same content, a synthesis unit weights the OFDM symbols of the same content with the weighting factors and then combines the OFDM symbols of the same content among equalization data.
