    摘要： A channel characteristic calculation unit 23 estimates channel characteristics based on SP signals included in received signals, and a symbol interpolation filter 24 frequency-shifts frequency transfer characteristics and filters output signals of the channel characteristic calculation unit 23. A filter control unit 27 estimates channel characteristics based on CP signals included in the received signals and observes the estimated channel characteristics to determine a shift amount by which the symbol interpolation filter 24 frequency-shifts the frequency transfer characteristics. The symbol interpolation filter 24 frequency-shifts the frequency transfer characteristics based on the shift amount determined by the filter control unit 27.
