A transmitting device includes a transmission signal generating unit configured to generate a transmission signal by inverse-Fourier-transforming reference signals and data signals mapped to subcarriers and a transmitting unit configured to wirelessly transmit the transmission signal. In the transmitting device, a total power level allocated to signals to be transmitted in a time slot is equal to a total power level allocated to signals to be transmitted in any other time slot, and a power density per unit bandwidth of the reference signals is greater than a power density per unit bandwidth of the data signals. This configuration makes it possible to equalize the total transmission power level of all time slots and thereby to improve the power amplification efficiency. Also, with this configuration, since the reference signals are transmitted with a higher power than that for other signals, it is possible to improve the accuracy of channel estimation.
