There are provided a correlation calculation unit that takes a cross-correlation between a signal from which a DC component of an analog baseband signal is removed, and to which a known fixed DC offset is added, and a known signal, an inter-correlation peak phase difference detection unit that estimates a carrier frequency offset from a peak of the calculated correlation vector, and a residual DC offset estimation unit that estimates a residual DC offset component from a mean value of the sidelobe of the calculated correlation vector. |
