Abstract:
A radio transmission device capable of improving the reception error rate characteristics of a receiver. In this device, an FFT (Fast Fourier Transform) unit (102) subjects a transmission signal to an FFT operation, in which a signal in a time domain is converted into a signal in a frequency domain. A control unit (103) controls the transmission power of the FFT-operated transmission signal in the frequency domain. An IFFT (Inverse Fast Fourier Transform) unit (104) subjects the transmission signal having its transmission power controlled, to an IFFT operation, in which an inverse conversion is made into a signal in the time domain. A transmission RF unit (106) transmits the IFFT-operated transmission signal on a single carrier.
