A modulator generates a modulation signal from an input signal, and a serial-parallel converter generates a subcarrier modulation signal from the modulation signal. An IFFT unit performs an inverse fast Fourier transformation on the subcarrier modulation signal to generate first data. An operator multiplies respective elements of the first data by amplitude coefficients, and further adds dispersion coefficients to the multiplication result, the amplitude coefficients being real numbers other than 0 defined for the respective elements, at least one of the amplitude coefficients having a value other than 1, the dispersion coefficients being complex numbers defined for the respective components, and at least one of the dispersion coefficients having a value other than 0. Then, data symbols are generated based on a calculation result. A transmitter transmits a transmission frame including the data symbols to another apparatus via an antenna.
