mapping means for converting data to be transmitted into a data group correlated to respective sub-carriers; inverse Fourier transform means for converting the data group into a time series signal; and means for creating a transmission symbol for radio transmission from the time series signal. The mapping means correlates data to be transmitted to a sub-carrier different from predetermined sub-carriers positioned at an identical interval on a frequency axis. De-mapping means of a reception device outputs the data correlated with a sub-carrier different from the predetermined sub-carriers positioned at an identical interval on the frequency axis, as data for restoration.
