RECEIVER, INTEGRATED CIRCUIT, AND RECEPTION METHOD

摘要

Channel characteristic calculation unit 23 estimates channel characteristics based on SP signals included in received signals, symbol interpolation filter 24 is able to frequency-shift frequency transfer characteristics and filters output signals of the channel characteristic calculation unit 23. 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.
