To provide a receiving device for an OFDM which is provided with an interpolation filter device reduced in circuit configuration, and to provide a filter device reduced in circuit configuration.
The receiving device comprises a symbol filter 40 which is equipped with a fetching part 41 for fetching an SP signal out of four signals, a multiplier 42, a coefficient selector 43 for selecting the coefficients in accordance with a tap where the SP signal is located, and an adder 44. With the coefficient selector 43 for selecting coefficients corresponding to the SP signal, it is unnecessary to be equipped with the multiplier 42 every coefficient and the number of the multipliers 42 can be reduced. Thus, the circuit configuration of the symbol filter 40 can be reduced.
