Patent ID: 8265043

Claim:
A transmitting device for sending a transmission signal modulated according to OFDM, comprising: a transmission signal generating unit configured to generate the transmission signal by inverse-Fourier-transforming a reference signal and a data signal mapped to subcarriers; and a transmitting unit configured to wirelessly transmit the transmission signal, wherein a total power level allocated to a first signal to be transmitted at a timing when the reference signal and the data signal are frequency-multiplexed is equal to a total power level allocated to a second signal to be transmitted at a timing when only the data signal is mapped; at the timing of the first signal where the reference signal and the data signal are frequency-multiplexed, mapping of the data signal to a predetermined subcarrier is prevented and a power density per unit bandwidth of the reference signal is greater than a power density per unit bandwidth of the data signal; and the power density per unit bandwidth of the data signal in the second signal is the same as the power density per unit bandwidth of the data signal in the first signal.
