A multicarrier transmitting apparatus includes a subcarrier mapping unit, an IFFT unit, and a signal transformation value separation unit. When the subcarrier mapping unit transmits first reference signals and second reference signals continuous in the time axis direction, the subcarrier mapping unit outputs a multicarrier signal in which the first reference signals and the second reference signals are allocated to subcarriers continuous in the frequency axis direction. The IFFT unit performs an inverse Fourier transformation on the multicarrier signal output from the subcarrier mapping unit to output signal transformation values in the time axis direction. The signal transformation value separation unit separates the signal transformation values output from the IFFT unit into signal transformation values associated with subcarriers to which the first reference signals are allocated and signal transformation values associated with the subcarriers to which the second reference signal are allocated.
