Abstract:
1. A receiving device, comprising: a receiving unit that receives a broadcast signal in which a guard interval copied from a tail part of an effective symbol including broadcast content is added to a head part of the effective symbol; a guard adding unit that adds the guard interval included in the broadcast signal received by the receiving unit to the tail part of the broadcast signal; a fast Fourier transform (FFT) unit that performs FFT on the broadcast signal to which the guard interval is added; a synthesizing unit that synthesizes a fixed component, which is fixed between carriers of the effective symbol, included in inter-carrier interference (ICI) in a broadcast signal on which FFT has been performed in view of an adding position of the guard interval in the broadcast signal and ICI in a broadcast signal on which FFT has been performed without considering the adding position, according to an addition amount of the guard interval; and an ICI calculating unit that calculates ICI to be removed from the broadcast signal on which FFT has been performed based on the fixed component synthesized by the synthesizing unit.
